jump gives a big boost right off the bat, no acceleration times, and since it is cheap, it can be used as a tool to gain, or lose distance from or to enemies in the early to mid game and is reliable in the late game also. the only problem is how it propels you into the air, so you still have to put at least 1 flight for every 5 jump for it to be the best, unless your a melee character, because you can just use a grapple plunger.
