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.
Started with Gnome, then i3, Hyprland and now Sway. Gnome not being designed around customisability made me switch to i3. Hyprland has had some stability issues and regressions that annoyed me and so I switched to Sway. Thinking of trying out river at some point.
I think if I reccomend linux kde to anyone new itll be gnome with a few extensions, since plasma is easy to break imo. A lot of default plasma configs are basically cleaner/customizable windows clones tho so it might be an easier transition, it immediatelt felt familiar when I was setting up cachyos. Feed like gnome couldve scared me off, especially since I didnt know about the extensions and how easy it was to get proper menu. Once I had like 3 extensions, it felt good, was using the computer like normal and forgot I had swapped to gnome to temporarily test it.
I really like gnomes look with a few extensions tho, with plasma I feel the constant need to tinker just because I can and its two clicks away, with gnome I just use my computer and the extensions just work, not as much customization, even for placement, but definitely a lot more useful extensions that just work.
