I’m looking for something simple that just works, with few crashes, few bugs and good community support. I’m moving away from Manjaro Cinnamon unstable branch to Ubuntu 20.04 and want a stable desktop environment. I only want bleeding edge software, but I want a stable foundation.
The original 4.0 release was actually a release candidate / beta release. KDE has had a bad rap since but in general has been very stable (unless you’re on wayland, there are still some bugs there).
I’ve been on Plasma Wayland for a year or more now, it’s really good. It got my 2-GPU, 6-monitor desktop setup stable as a rock vs. the fustercluck that was X11 trying to manage that.
