Since I am all about pure power movesets (most of the time), I would say Superpower-but pp wise (which I am becoming more aware of (like having only 5 pp moves is not wise)) Low kick would also be good because a lot of black and white are more-or-less heavy. The Reason this is not a answer is because I don't have a real answer going. But going of this advice, I advise you to consider both and choose based on what you think would fit your Aggron the best.
