COSMIC most of the time and then gnome as a fallback when I run into any temporary issues I can't work around.

I do this with a custom bluebuild image I made that uses ublue (fedora 41) as a base and then added cosmic on top along with some other layers that I need/want.

I really love both esp after KDE 6. But I use Gnome, KDE treats multiple monitors as separate entities I find the bugs distracting and there's only so much customisation I need. I slap open bar on and get to work.

Gnome on one machine, LXDE on another.

I use Gnome on my main laptop, a Thinkpad P50. I bought it with a dock thinking I'd use it at my desk and on the sofa but it's a bit of a beast so that stays on my desk and I use an L440 with LXDE on the sofa. Considering trying LCARS on the sofa machine.

At the moment, my main machine is on KDE because it has very good Wayland support and isn't Gnome. I prefer Cinnamon

Kde because i want customization and standard is also ok. I tried gnome but did not like that extensions were required for tray icons etc. Gnome is otherwise good.

I3 and hyperland i dont get. Some windows should not be very large no matter how much free screen space you have. Example is calculator or old school chat applications like pidgin. No native standard set of applications. Everything must manually be added and custom, like everything in kde settings(sound output, network settings, screen size etc). Waiting for when applications can recommend its screen size to the window manager.

I have an i3 and a hyprland installation.

I like tiling wms but Wayland still has some annoying issues so I like having the more stable i3 installation on my main computer.

KDE Plasma 5.

It's default on Slackware =P

KDE, because I'm too lazy to switch back to XFCE, which offered every feature I already use in KDE except without the stuttering, the bugs, and the update cycle that breaks things way, way too often on a rolling release distro.

Or openbox. My old laptop has openbox, but that's more for screwing around with EWW than doing day-to-day things.

Plasma, because I want things to Just Work(TM) and the customizability and modernity are neat. I like right click --> pin to top/bottom as well.

I currently use Gnome on my laptop, but I've toyed with returning to KDE for a while. I used KDE briefly back in the v3 and v4 days felt like it was a bit bloated compared to Gnome v1 and v2. Cinnamon is nice but a bit heavyweight on graphics. I should probably return to XFCE or Mate.

I use herbstluftwm. The configuration is straightforward and it fits my minimal needs.

I use KDE plasma 5 atm and i planning on an upgrade to 6 soon; but it's my daily driver so I've dragging my feet on it for a couple weeks now.

What happened when tried troubleshooting those problems you had?

I'm currently using Cinnamon because I thought it would be better than Xfce. While I do think that Cinnamon looks better, there were some minor things that I preferred with Xfce. I want to try Mate and maybe some of the other DEs if I can find a good distro that has them but I may go back to Xfce the next time I install Linux Mint.
