All mountain I would probably go with next year's Uninc replacement, the Easy Living. I'm not a big fan of Burton boards, but I really enjoyed that one for sure.
I really don't like anything Burton has to offer in the pure freestyle realm. The Fix is too stiff and just feels dead, the Dominant is decent, and the Hero is alright, but I'd rather be one of the other sweet jib boards on the market, like the K2 WWW, Rome Artifact, Ride Kink; there are so many great freestyle and jib boards on the market right now, there isn't much reason to go with B.
I'm a huge fan of the Malolo for powder and packed powder freeride conditions, and the new models with the S-rocker are fantastic. Just enough taper to sit back in powder, but still super stable at speed on groomers. With the Vapor out of the picture, my next pick would be the Custom-X, but that sucker is stiff.
For progression, I don't think enough good can be said about Burton's LTR system. Sure they aren't perfect, but they're soft, and better than most beginner boards available in rental shops; the quick-discs are a dream when dealing with rentals in lessons. The kids LTRs with the convex base (toe-to-heel) and reverse camber are amazing to teach with, you can get 3-year-olds up and ripping so much easier.
