The Marvel Now books are pretty good. Some of the folks above have mentioned the really goos ones, All New X-Men and New Avengers are great so far. And the fantastic Four and FF are really fun. If you haven't read Wolverine and the X-Men you should, it has all the great components of creative comic writing and excellent art. The new Deadpool book is crazy and awesome, written by comedien Brian Posehn.
As stated Marvel did not reboot their universe, they simpley shook up artists and books, challenging the bullpen to write from new fun perspectives. The also \ created a few new titles for the universe to evolve.
