As someone thats been on the osx train since 10.2. I get somewhat amused by the "OSX N+latest is the worst OSX" comments.

I had the (dis)pleasure of using someone's 10.1 machine, oy wow, surprised that even got released.

As a counterpart, mavericks has been the most stable osx for myself so far. Additionally the battery life improvements gave me an extra hour on battery alone. You can pry mavericks from my cold dead hands at this point. The energy tab is also really useful at finding out what is using up battery needlessly (looking at you chrome/firefox).
