I always wanted to be able to fly, but given how often superheroes in stories lose their powers, I'd be terrified of losing that ability and winding up dead, and what if I crash? So I'd have to be careful.
But flight is quite limited, really, when you think about it. I can't, say, pick up someone else and bring them with me. Now matter manipulation, that'd give me the ability to move the molecules in the air around me, effectively giving me flight powers, plus a kind of telekinesis. So I'm going to go with that.
