Linux

Plasma, but I'll be moving to cosmic as soon as it enables auto power off of monitors on idle

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.

I'm running MATE on my laptop. It gives me what I need (a task bar, space for some instrumentation, the usual desktop functionality, a way to start applications) and nothing that I don't care about (wobbling windows, compiz, stuff like that). My DE is a tool; I use tools that don't get in my way because I have work to do.

I might give COSMIC a try in a few months, I haven't decided yet.

Qtile, just because it's Python-based.

COSMIC. I was using Hyprland before but I wanted to try the alpha. I found it stable enough for my use-case so I stuck with it

Currently I am on KDE, but I am an xfce lover. I can't wait for the next xfce update and for Cosmic.

I am living KDE almost default. I have the impression that with too much customisation problems come.

Xfce is rock solid and rock solid after customisation too. It is truly amazing.

Gnome needs far too many extension for me to be usable. And so I avoid it.

Cinnamon is great too, but it's in the middle. If I don't want to use Wayland, at that point there is xfce.

KDE Plasma because it's the one I like. If it disappeared tomorrow, I'd use Xfce.

Xmonad with XFCE in no-desktop mode.

I can use the xfce tools to configure things like mouse and screen settings, but visually it's just xmonad.

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.

KDE Plasma 5.

It's default on Slackware =P

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

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 recently made a new linux install (to replace my constantly breaking, likely due to my own doing Manjaro install). I went with Cinnamon initially, but in order to try out Wayland, I moved to KDE plasma.

I'm on NVidia, with two different resolution screens. Which causes occasional problems. But overall it's fine.

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.

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.

KDE Plasma because I can make it look, feel and work mostly like Windows. I have to use Windows at work and don't want to have to think too hard about differences between computers I use at work vs. at home.
