Had To scroll way too far to find Cinnamon so here's back to the top.

Herbstluftwm with dmenu. Just a windows manager. I've gotten used to using the command line for things I used to rely on a DE for.

Sway for a laptop, Plasma for desktop.

Had you have asked me a few weeks ago, I probably would have said Sway for both,.or maybe Gnome for the desktop... But I decided to check out KDE again for the first time in like 20 years, and while it's still kind of a hot mess it has come a long way.

Well, for me it would be the setup i am now using since about 15 years:

WM: flwm Filemanager: ROX-Filer Background: feh

... and a ton of tools i accumulated over the yesrs

Gnome. It looks so much more modern, but I would like a layout like Plasmas more than the gnome one

Xfce

Twm, I'll extend it as needed.

I just don't like KDE and am not a big fan of stock Gnome either but the PopOS version with COSMIC features plus the Dash to Panel extension make it pretty useable

True people only use i3 or the-other-i3-for-wayland

/s, of course. But still my personal choice

I'm a long time supporter of Xfce, but I have to say Cinnamon these days. It's light on resources while being feature rich. Also it's the default on Mint and it just works.
