The fact that the company Valve went with KDE instead of GNOME for there popular linux device seems to indicate that it is at least stable. I could get some user testomonies on /c/Linux about KDE if you want?
Valve went with KDE not because it is stable, but because user interface can be customised with it catering to gamers. GNOME is more rigid and stable. The exact same reason goes for Arch, quickest firmware and kernel updates to leverage maximum performance per watt and to buy maximum time for optimisation. Arch is not known for stability in the way Debian/Ubuntu LTS are known.
