Invisibility is creepy, and there's the whole clothes and food issue. Super strength seems a bit pointless apart from impressing blokes in a pub. Teleportation is a possibility. But come on, it's flight isn't it? Although they never seem to address the problems of warm clothing, goggles and just getting lost in the air. I think you would need a decent flying jacket and some goggles with a heads up GPS system. That would work.
