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 Xfce with a swap of the window manager by Bspwm. I got the easy to configure Xfce status bar (instead of things like polybar and others…) and also the Xfce terminal, file manager… The window title is written to the status bar. I use Super + B/N to switch the workspaces. Some apps are set to floating mode like the image viewer, the calculator… So everything can be displayed in a good tiling WM and I don’t need to manipulate windows.
