Linux

I used Enlightment for the last few years, but switched this year to XFCE because i like the look more. I'm using old-as-fuck-hardware and both DEs work good on my machines.

Usually KDE, but I'm messing around with qtile atm.

KDE on my main gaming PC, or if I want something that looks really modern and sleek without tons of setup/tweaking on another PC.

Mint with Cinnamon if I want a #justworks setup that is rock stable and I don't need to look sexy.

My side business laptop uses LMDE with Cinnamon for that reason. I need that thing to be rock stable and dependable at all times.

Cinnamon has been more stable for me than any other DE, and in my experience, is just as performant as other low-spec favorites like XFCE. My fresh install of LMDE with Cinnamon right after boot uses about 850MB of memory. My testing with XFCE was about the same, maybe 50-75MB less, which for my use case is effectively identical.

Not crapping on XFCE though, I like playing with it on one of my old thinkpads. Not a fan at all of Gnome, I've tried to like it for years, but I just don't care for it, and I experience quite a few bugs.

I plan on trying the new Cosmic DE soon, it seems like Gnome done better, and I could see myself liking it from the reviews I've watched.

OpenBox but that's a window manager, not a DE.

trinity because it's lighter than almost everything else while having more features than almost everything else

Currently, Plasma. But I have ADHD a bit, so I’ve gone back and forth between that and Gnome mostly. I do like Cinnamon and I really want to spend time with Xfce and maybe others just to see what feels most comfortable right now. I’m trying to go for keyboard comfort these days, so we’ll see where I land at some point!

OK so I have used several DEs but right now I'm on Plasma 6 because frankly, it's the best out there. It's easy to use, customizable, intuitive and looks nice. Is it on the heavier side? Yes, but that's okay. Also it helps that I have learnt the keyboard shortcuts on this.

I have used XFCE, Mate and Cinnamon in the past. If KDE somehow vanished off the face of the planet, I would likely switch to XFCE because it's light, customizable and fully functional.

Xfce. Partly because I've used it for a long time, but mostly because it does what I need it to do and little else.

XFCE.

I recently switched to it after a year or so with KDE. Deff see some improvement in terms of battery life with my laptop, but I'm still not used to the lack of WinKey+Num shortcuts (I'm aware of docklike, but I need labels for open windows).

None. Openbox WM with Tint2 as a rudimentary system bar, Rofi as launcher.

I use Gnome, but I just wanted to say Cinnamon is fantastic (probably my first choice if I weren't on a laptop)

KDE Plasma.

GNOME kind of looks nice but is too strict on customization.

Gnome.

With NoMachine to my Windows Host, hot keys go to the host as intended.

Rustdesk can't do it in any config and they don't care at this stage.

KDE for my main PC. Pretty with floating panels, KDE Connect, QT apps are often the best apps in their class and are perfectly integrated (FreeCAD, krita, okular, kdenlive, vlc, dolphin, etc...) And konsole is also very full featured.

I don't know what KiCAD uses, but it also seems very well integrated into the KDE desktop unlike most gnome apps.

XFCE on MX Linux for an old Intel Compute Stick to keep it very usable.

KDE, because despite my bitterness for the loss of Unity 8, I know it's merely nostalgia for me. I want something I feel like I can make my own without too much difficulty.

I use DWM in place of a window manager because I love the lightweight, minimalist base, and i like to customise my setup very finely. (I use Arch btw)

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.

Sway on a chromebook with 4gb ram, sway on thinkpad t430, xfce on my gf's laptop, and gnome on my gaming rig that will go soon either cosmic or just sway. For me sway is thewinner. Sway with me... Marimba... Lalala

Edit: also gnome on the kichen pc with touch. Gnome is the only one that works fully on touch.

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.

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.

For my main workstation and main laptop:

• Cosmic themed GNOME - I just like the way it looks and works without any changes. The basic tiling functions are something I find helpful at times too.
• Plasma 6 - It works pretty well and looks nice. I don't do a lot of customization, so it's not a big deal to me. For my other machines I'm currently using Cinnamon, GNOME, Budgie, and LXDE.

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.
