Intamin's great and all, but I'd say B&M. The really good intamins are the airtime machines and accelerators, and there isn't much else that really stands out for me (plus some are just bad).
B&M has the airtime on a dozen or so hypers, the intensity on the inverts, some with nice gracefulness, and some other fun stuff. Other than stand ups, there isn't really a bad B&M from what I've experienced.
