I'm not a beginner anymore, but I'm much less interested in technical tinkering for its own sake than I used to be. These days I just want my computer to work properly without too much intervention from me.

I've been using Kubuntu for a number of years, but I'm also hearing increasing complaints about how Canonical is running things. I don't think I'm ready to switch to a new distro yet, but it wouldn't hurt to know what's out there.

Is Kubuntu still a good choice for an "it just works" KDE-based distro, or has it been surpassed?
