I think NixOS is awesome, but it certainly doesn't offer "access to (basically) all Linux-capable software, no matter from what repo." - at least not natively. You can do that through containers, but you can do that with containers on any distro. Where it shines is declaring the complete system configuration (including installed programs and their configuration) in its config file (on file-based configuration, I wouldn't really consider blendos a viable competitor).

I don't quite agree with this. In NixOS you can write custom expressions that fetch software from any source, and stitch them into your configuration as first-class packages. So you do get access to all Linux-capable software natively, but not necessarily easily. (There is a learning curve to packaging stuff yourself.)
I use this process to bring nightly releases of neovim and nushell into my reproducible config. Ok, I do use flakes that other people published for building those projects, which is a bit like installing from a community PPA. But when I wanted to install Niri, a very new window manager I wrote the package and NixOS module expressions all by myself!
Another NixOS user (and minor package maintainer, if it matters) here. Essentially, NixOS is actually rather simple to write a configuration file for a particular program once you get the knack for the nix language and learn how to workaround the sandboxing. I would actually consider it substantially less involved as compared to (for instance) creating your own Debian package.
However, getting to this point will take a bit of effort, and this step is more or less obligatory to use software on NixOS, whereas it generally isn't (but still is a good idea) on other distributions.

(There is a learning curve to packaging stuff yourself.)
"Learning curve" is an understatement. Nix is one of the most poorly documented projects I've seen, next to openstack. Coming into it with no background in functional programming didn't help.
Maybe I shouldn't have tried to package openstack on nix.
But I've tried to package other stuff, like quarto, and that was a nightmare. Nixpkgs didn't have an updated pandoc and I spent an eternity asking around for help, to try to package it. An updated version just got pushed to unstable a few days ago. The same matrix channels I joined to ask for help have been discussing this since then. Props on them for getting it working, but anyone who says that you can easily package anything, is capping. You need to have an understanding of the nix language, nix packaging (both of which are poorly documented), and a rudimentary packaging ecosystem of what you are trying to package.
Don't even get me started on flakes vs nonflakes.
I still use nix-shell for all my development environments, because it's the best way for reproducible environments I can share I've found.
While I’ve looked into Fedora Silverblue, that distro is limited to only install Flatpaks, which is fine for “apps”, but seems to be more of a problem with managing system- and CLI tools.
No. Your understanding to Fedora Silverblue is wrong. I can just run rpm-ostree install package.name in Silverblue, like other Fedora spins. The small disadvantage is that I need to reboot to apply this update. (re-construct)
but doesn’t that result in new A/B snapshots, or something like that?
Well, you can call it snapshots, but there is no need to think about it. In most cases, the system points to the newest snapshot (deployment 0). If a rollback is needed, I can pin to the older deployments. When a major change is to be applied (Like bump Fedora version), I'd manually mark the current deployment as dont-auto-delete.
Sure, but I’d like to have a more seamless experience, i.e. not having to open/start any “containers” or something like that.
I never used toolbox in my Fedora Silverblue system. I feel that I can't tell the difference between using Silverblue and the default Fedora spin
Thank you; that was very insightful 😊
Also: I think rpm-ostree only supports rpm-based packages, tho; right?
Can I install .deb software too?
And is there any kind of system-as-a-config-file kind of solution available like in NixOS or blendOS?
For other systems I think distrobox and toolbox are kind the intended way to mess with them. For configuration as code ansible is a popular answer.
Calling NixOS the new arch is needlessly insulting lol.
I mean seeing how people here act after having been on nixos for a few weeks I would say it's an apt comparison. I swear we weren't that obnoxious when I started using the distro in 2019 D:
NixOS is uncomparable.
It just makes so much sense in a way other distros don't
Fedora Silverblue and NixOS looking very interesting ✨👀
Lots of great answers here already so I will only address a couple of things that haven't been mentioned:
Regarding Fedora Silverblue:
Regarding Vanilla OS:
What are your thoughts on the ~~three~~ four distros mentioned above?
It's a question of polish if you'd ask me. With Fedora Atomic Desktops and NixOS being advantageous due to being more established and better funded. I wouldn't write off Vanilla OS yet as they seem to know what they're doing. Though, I wouldn't keep my hopes up for blendOS as its main developer was unaware of which MAC was configured by default on blendOS (spoiler alert: none, at least at the time).
Furthermore, NixOS is literally its own thing and unfortunately infamous for its steep learning curve. If you can afford to learn and conquer NixOS, then NixOS should be the recommendation; unless (like me) you seek SELinux on your systems.
Between Fedora Atomic Desktops and Vanilla OS; Vanilla OS is still in its major rewrite/revamp. The alpha builds are there, but I wouldn't recommend using those on production machines. Fedora Atomic Desktops, on the other hand, has been going strong for a while now and the uBlue-team has even succeeded in making the OCI-stuff accessible for the general (Linux) public. So if you want to switch now and NixOS is/seems too hard; then Fedora Atomic Desktops it is. On that note, I recommend to check out the uBlue project.
Which ones are the most interesting, and for what reasons?
Honestly, all of them are really interesting, but NixOS does the most unique stuff; with only Guix doing something similar within the Linux landscape. To give you a taste of some of the wild stuff found on NixOS; there's the so-called Impermanence module which -to my knowledge- happens to be the closest thing to a usable stateless system we've got; period. Consider reading this excellent blog post in case you're interested to know what this entails.
Thanks for the detailed response.
I'll probably go for either a Fedora Atomic Desktop or NixOS.
You look at defaults and think this is linux.
Look again at Fedora Silverblue /any other desktop variant. VanillaOSses apx is just a wrapper around distrobox, which is preinstalled on ublue even.
Apx installs apps on containers just as it is possible on Fedora Atomic (the general name for all immutable desktops). You can also layer and remove apps to or from the base OS which is sometimes needed or nice for speed.
On Fedora Atomic you have
You look at defaults and think this is linux.
What do you mean by that?
On the Fedora Atomic website, they write:
Project Atomic is now sunset
The Atomic Host platform is now replaced by CoreOS. Users of Atomic Host are encouraged to join the CoreOS community
Do you think CoreOS is a good fit for a desktop?
I always thought it's more of a server distro.
On a related note: Would you recommend Fedora Silverblue?
Oh no. The rebrand is not done. There is no Atomic site yet, Atomic= Fedora Desktop with OSTree (Silverblue, Kinoite, Sericea, ...)
If you like GNOME, yes I recommend Silverblue a lot.
Fedora has a very different system of the core distro. But with defaults I mean that they dont have apx by default but the same underneath.
You could use a bash function for DNF for example, but in general it is
distrobox-create Fedora39
distrobox enter Fedora39
sudo dnf install PACKAGE
distrobox-export --app PACKAGE
for GUI packages
You van both use rpm-ostree and toolbox to install regular fedora packages on silverblue/kinoite
I would check out something like universal-blue.org. It is fedora silverblue but with fixes that make it more usable (like codecs by default). It also ships distrobox right out of the gate so you can use that for apps that aren't in the fedora repos, copr , or flatpak. You also don't have to layer packages if you install via distrobox so I think it ends up being pretty handy for stuff that you want that isn't available as a flatpak. Finally there are many different images for all different desktop environments so you can switch between them just by using rpm-ostree rebase and the link to the different image.
What is your usecase?
This is the key question.
Daily driver;
Is there something that attracts you to NixOS for that purpose?
I've got Nix OS running on one of my computers, and honestly, haven't found it to be particularly notable for those usecases.
Dev work is not specific enough. Pip is a nightmare because it just wanted to modify folders that were read only and you never know what it wants to do to your system. Your experience may vary depending on how much the language package manager assumes about your system. If you're in a container, it will work perfectly, though
Firefox just works, and I installed Steam from nixpkgs and it worked after enabling a few settings. Then I just enabled Proton on every game and it works okay, with a few weird bugs sometimes (although I blame Gnome for messing up alt tabbing sometimes)
So none. Didn't even have to look further, as they're all dead to me.
Nix is better because you can use a lock file to fetch the exact revisions of each software. Even proprietary stuff is hashed so when you download it, it's checked to be bit identical to the lock file hash before it's installed
This means your setup on another machine is the same as long as the lock file is the same.
Also you can switch to an older revision, mix and match stable and unstable, keep your whole setup in a git repo. It's basically everything you ever would want from a package manager (reproducible builds already done for the minimal version, soon coming to all 80,000 packages)
I would guess what distro you use, but I think I can guess.
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
