From my perspective Maui is EXACTLY the distro you are looking for 
Much more stable in terms of not crashing and being tested before releases, but receiving regular upgrades to new Plasma versions (2-3 weeks after its original release, after testing). As for the other software, Ubuntu does a pretty nice job of keeping up with the new versions, but if you find something missing, you are 99% sure there will be a PPA for it or a .deb that you can fetch from net. I've also tried numerous distros, also been down the rolling release road (that didn't go quite well for me either) and up until now was never 100% satisfied. Now I must say that I am
PS: I've tried Neon as well, but it feels quite unfinished and some crucial end-user things tend to have problems (samba sharing, bluetooth etc.). Maui, on the other hand, always worked like a charm in these areas (for me).
