In my opinion super speed is the most overrated power. All it really does is making you move faster and unpredictably (please dont come with this force=mass x acceleration stuff, there are plenty of real life boxers with fast punches yet they all hit like feathers, even Ali yet he had a lot of speed and mass). I'm not saying speed is useless, but I just dunno why people love that power so much.
Most underrated? I dunno. Maybe durability (or strength I dunno).
Anyways which power do you think is the most overrated power, and the most underrated power?
