Why not give Manjaro a try? It's based on Arch but the devs maintain several repositories - unstable, testing and standard. Unstable is bleeding-edge - packages are available as soon as possible; this is basically the same as Arch. By default the desktop installation uses the "standard" repository, which simply delays package upgrades anywhere between 1 and 2 weeks and releases them as batches.
I've been using it as a daily desktop driver on different machines for about three years now, and a package udpate has never ever broken anything. Granted, I never used NVidia or Gnome like this person: >>66686764
. From my experience it's stable enough to serve as a server or for corporate infrastructure.
