Telekenisis, by far. Think about it, if you have the power to control things at a distance, in any angle, at any time, you essentially have the power to mimic every, single super power in existence. Want fire conjuring? VIBRATE SOME ATOMS, you want time stopping? ACCELERATE THINGS CLOSE TO THE SPEED OF LIGHT, you want the power to mind control? REDISTRIBUTE NEURAL PATTERNS IN PEOPLE. You are the controller of matter, the shaper of space and time, the avatar of destruction, the holder of creation, the god amongst men.
If you had three wishes (and they couldn't be for more wishes) what would they be?
