Linux

XFCE. I also like tiling WMs, but I often have to share computers and they are too unintuitive for the rest of the family.

i3. Superb for keyboard-driven environment. Ultra fast, so responsive and configurable. The best.

Sway, will try the new cosmic once its in beta

I am extremely basic and I'm using the XFCE that came with Linux mint. I don't need anything fancy.

KDE for its Wayland performance and features and occasionally I switch to hyprland if I need a more focused work environment.
In the past I used Cinnamon but it became ever more buggier on Arch and due to lack of Wayland support still it was a dead end anyway.

MATE (prn: MAH-Tay)

because it comes with standard Trisquel and is a smooth DE experience.

I use i3. Pretty bare bones, so it took me a while to get productive with it. But it's all exactly how I want it, it's all mine.

Depends on the computer I run. On fast computers (more than 5,000 passmark cpu points), i use gnome on whatever distro. On mid-speed computers (1000 to 5000 points), I use linux mint with cinnamon. On very old computers (400-1000), I use debian with XFce.

Gaming PC: GNOME (it works fine and I don't care about much else there)

Laptop: dwl (dwm for Wayland) and suckless tools. Ultra lightweight and comfy for browsing and watching videos. Usually at the same time.

Long time i3 user, recently switched to Hyprland+Wayland. I just don't like mice, don't enjoy using them, and I find the snappiness and responsiveness of keyboard-centric workflows very fun and enjoyable.

I am a software developer, and I am very impatient when it comes to my tools: I like my feedback cycles and interactions to be as tight as possible. This limited study from 2015 showed that developers, on average, spend ~26% of their productive time on stuff that is not related to either code editing or comprehension, including 14% spent on UI interactions. Tiling window manager allows me to streamline most of these interactions through hotkey bindings and shell automation, >!so I prefer spending literal months polishing my dotfiles instead!<

I use gnome on my main machines, but looking to migrate to cosmic, and I use xfce on more limited devices.

I like the kde project, but I tend not to use it, because I find it a bit overwhelming, even after customizing it, it's hard to explain. I have issues with too many elements in front of me.

GNOME, because I started with Red Hat 6 and I'm used to it, on Fedora Silverblue, because I have a long history of fucking up my PC and that makes it harder. For remote machines XFCE because the mouse is cute.

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.

Budgie, because I like the way it looks.

Used Mint with Cinnamon for a long time, but always wanted to try KDE after distrohopping a bit. Had it on when I switched to Arch, but didn't like how slow it felt on my old laptop so I tried LXQt and then XFCE. I wanted a modern lightweight environment with Wayland support, but I'll have to wait for it to be implemented. In the meantime, I riced my XFCE just how I like it, and I really like how complete and responsive it is.

xfce, i dont need that other bloat.

GNOME because of PaperWM

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)

I'm on Hyprland mostly because of all the tiling window managers out there these days, it feels like the most usable default config and the ecosystem (e.g. hyprlock etc) feels pretty complete.

XFCE. it's dumb, simple, it gives you a panel to access your programs, your desktop icons, and nothing else. I just want my computer to let me do my things, not have a built-in 'brew a cup of coffee' button

GNOME. Love the simplicity!

Nobody uses cinnamon? Honestly - I really like using cinnamon with Debian. I heard that they promised not to fuck with the UI for no reason unlike... everyone! @Mwa Cinnamon is a fairly nice, easy to use desktop - I don't really care which is better, but if they change it, you have to re-learn it. Top tip for UI design - don't think that your users want to re-learn how to interact with your UI - they might go outside, or elsewhere.
