Agreed! I recently switched from a very custom Linux setup with a tiling window manager and all kinds of bells and whistles. The Plasma 6 release in combination with running NixOS which makes trying things out both easily and safely convinced me to give it a shot and I simply haven't left. It took some setup, of course, but Plasma is wonderfully configurable and has everything I wanted available with some tweaking.

Whereas GNOME and others required extensions, which are often out of date or somewhat sketchy -- before I could set things up how I like.

Big fan so far.
