>>6760017KDE is really comfy.
It is a bit buggy, but it seems pretty much stable on arch, at least, now. The only bugginess Im seeing lately is occasionaly some text in the start menu or the panel turning into boxes, and I need to kill and restart plasmashell on login to make it set the wallpapers and panel to the right monitors.
On kubuntus version of it, however, it frequently crashed and had to restart itself, much more broken. though it still restarted itself perfectly fine every time.
