Definitely give it a shot, especially if you already know C. Getting your laptop set up the way you want can take some time at first but libinput makes it easy. I've never had issues with Arch on my desktop + lenovo thinkpad, and I update it two or three times a week. It's honestly surprisingly stable for a rolling release, unless you don't know what you're doing. There has been a couple times where I've messed up a binary file and had to arch-chroot in from the install medium in order to fix things. This was on me and a learning experience. The Archwiki documentation is the best source of information on the internet. I use it constantly. The AUR is never ceases to amaze me. It has nearly anything you need, even proprietary software. I am always amazed when some obscure legacy software that I need has already been compiled into a package build on AUR. The PKGBUILD files are concise and easy to understand in case you need to make changes to keep up with updated software.

Also it allows for complete control over every aspect of your desktop environment. It makes things so much easier. Despite what most people say I think systemd is great. You can easily view your services or daemons and have complete control. It makes using my OS a breeze and I am able to pump out scripts, or even run projects through hypervisors quickly and efficiently. I will likely never go back to another OS or distro for that matter, so dive in!

I've been using arch for many years now. I've used various distros every once in a while, but I always come back to arch. When arch break it is probably a single package that is causing the issue, and there is likely a forum post explaining how to fix it already when you have an issue. However if I manage to break ubuntu for example, I always have a bad time getting the system back up without a reinstall. I haven't tried using BTRFS for snapshots yet, but I usually format my drive to BTRFS for new systems/reinstalls now, so I have the opportunity at least. Don't know if snapshots would have made a difference for the GRUB issue that happened though. Thankfully it didn't affect me as I use systemd-boot instead.

I also use Gnome, vscode and firefox. Don't know about matlab but there is a wiki page and an aur package, so I think it should work. For gnome if you use extensions, I recommend installing them from the aur, instead of from the web browser, as you won't need to manually update them. For vscode, there is an aur package for the official version from microsoft, but there is also a FOSS version on the main repo (though some extensions may not work/be available out of the box on that one).

One issue arch users may get after a while is the hard drive filling with cached packages. Pacman doesn't delete old packages from the cache automatically, so if you never clear the cache, you will get a copy of every version of every package you've ever installed in the cache. I've made it a habit now every once in a while I'll clear the cache, after an update and I've confirmed the system works after the update. There's a command "paccache" from the "pacman-contrib" package that's convenient for clearing cached packages.

My 2c would be yes only if you're specifically seeking out the bleeding edge and don't mind or enjoy doing the neccesary tinkering.

Alsp you have time in between now and a re-install I'd highly recommended trying to do you're day to day stuff in an Arch VM for a bit and see if it works for you.

I'm very biased, but try Gentoo. It's no harder to install than arch and has some very cool package management features, like USE flags.

I've been using ubuntu based distros but now i use CachyOS and Vanilla Arch Linux, and even though I didn't want to admit it at first, it's a better but similar overall experience. the package manager with yay is just so much better than apt

No, go straight to MX Linux you'll have Nvidia driver, and luks/btrfs and snapshot etc OOB.
