So far KDE is the closest to my needs and wants (very fast rendering, very fast dolphin, consistent UI, fast window switching and managing, the whole thing feels very snappy[0]). I just configured some shortcuts to manage windows approximately like I do in awesome-wm (tiling manager).
There are still thing that I don't like in it (configuration manager is overloaded with options and I don't always find my way through it).
I wish someone would do a regolith for KDE :).
[0] Truth be told I like the simplicity of the Gnome WM but it's way too sluggish.
