Linux

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

After trying mostly everything, I always come back to my "custom desktop": (openbox + xfce4-panel + thunar + xfce4-terminal + dunst) .. for the last 15 years or so. It doesn't get in the way, is fast AF, it takes very very little ram/cpu (4.5 Mb !!) and it has everything I need (even tiling via keyboard). It's VERY customizable and it does as I tell. No crashes, no weirdeness. It just works. I will probably move to labwc in a future, just because.. wayland. And now I'm about to use it on a steam deck... it's gonna be fun.

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

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

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.

I use hyprland with KDE as my fall back.

My hyprland config is 95% stable but some apps give me a hard time, so I'll just run them in KDE.

I find KDE just works. With a baby, things need to work more often than not.

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

Gnome. It just works out of the box and I can fly through it using the keyboard and touchpad without having to configure it first.
I've done the whole song and dance with tiling WMs, or going through all of KDE's settings until it was perfect, but I just can't be bothered anymore.

KDE Plasma. I like having a familiar start menu and keyboard shortcuts

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.

XFCE as I like the look of the classic Windows layout. Might eventually try out KDE for Wayland support but there's something about the simplicity of XFCE which I love.

I'm old, I come from old X11R4 time, motif, mwm, twm, fvwm, things from previous century. In modern Linux I used mostly gnome, and Cinnamon for a few years and tried to love it but cannot, I finally went back to Xfce because it works, it's simple, neat, nice, I have no icon on my desktop, I have a kind of windows 3 setup: a startup menu (and some quick launches), the window bar, the notification area with time etc

I'm using MX Linux for maybe 8 years now with Xfce

GNOME. Love the simplicity!

I used enlightenment for something like a decade. When Gnome hit the big time I used Gnome because it looked Nice and was very flexible. I went back to Mac and Windows Land for a bit, when I came back I went Gnome again. I just screw around for a day looking and picking plugins and fighting with it to get it exactly how I wanted it. After fighting with one of the older plugins that mustn't doing what I wanted to do I saw somebody mentioned using KDE. I tried KDE and sure enough every single thing I was plugging the hell out of Gnome for was a default setting in KDE. I'm currently running Plasma. I must say that Cinnamon's not bad either.

GNOME. Eagerly waiting for cosmic.

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.

Xfce... Because I donno, been using it for many years

Sway. Very customiseable and extremely snappy

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.

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.

I use Mate. When I first started using a Desktop in addition to terminals, it was with Redhat 6.1, Redhat came with Gnome-2, I got used to it. I didn't like the changes made in Gnome-3, so I switched to Mate which retained, or at least had the option to be configured to look as I was used to it, save for more refined graphics. It also works well remotely so that's another reason I use it as much of my work involves remote acess.

kde plasma, it's fast, it's pretty, it's handy, it has all the keyboard shortcuts.
