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.
Xfce for speed, consistency, and reliability. For most of my workflow I began avoiding configuring a DE as much as possible by relying on AutoKey, Input Remapper, and simple terminal commands, because I can import those to fresh installs way easier.
I moved away from Plasma due to too many small yet annoying bugs.

Plasma does seem to have a lot of small annoying bugs, like rnow I have to click a widget so it loads on my desktop before dragging, if I just drag plasma closes out of the editor and my screen goes black for a second.
