After trying out Cosmic, Gnome,KDE Plasma, and Hyprland, I feel like plasma is the most usable for me coming from Windows. It solves the gripes I had about lack of customizability while still starting me off with a familiar homebar. I will be going back and forth with gnome for a while.
I really like gnome and the sliding desktops, and all the extensions seem to make it very customizable as well, but not directly like plasma, instead you mix and match (or make) extensions to get the look you want. (correct me if im wrong, I used it for a day)
Hyprland seems very nice for multitasking but the keyboard focus of the presets ive tried doesn’t really appeal to me, I like being able to just use my mouse sometimes.
Cosmic, is definitely an alpha and im interested to see what it becomes, wont be using it now.
I use Mate on my laptop; before that I used Cinnamon.
To be honest, DEs are basically terminal window managers for me. If I didn’t need a graphical web browser for everything I do (because that’s basically what software is these days - shit you log into from a web browser) I’d probably be using GNU Screen or possibly Twin to manage multiple shells instead.
If the drag-and-drop functionality of modern DEs wasn’t so helpful I’d probably still be using twm because I like stuff that does what I need, and otherwise stays out of my way.
