For me, if I'm missing something, its a pacman or AUR search away. If I need development features of anything it exists as a -git repo as well, and I can super fast insert my patches and get what I need immediately. No updates or any of this insanity stand in my way, and my systems been stable for almost three years since I built it, I just subscribe to the Arch announcements mailing list for major updates that might cause problems. We just got Linux 4.4 yesterday, and I booted today and kept on rolling as per usual.
