I am totally the beta type of person however considering generally the first three releases of a new OSX, and the first one or two versions of iOS from Apple feel like alpha versions lately I think I will hold off. They don't get things ironed out until x.x.3 for iOS and x.x.4 for OSX it feels like (and unfortunately sometimes they never get that high before they come out with the next version and create more bugs!)
