It can be different depends on which criteria it is.What's the criteria? Height? Speed? Flow? Variety of jumps and combos? Difficulty? Consistency? etc.
No doubt Midori is the best jumper, better than most of guys!
Among the current ladies, I think Gold and Yuna are the best overall - speed, flow, height, distance, great air position, difficulty, consistency (Yuna is very consistent), etc. Liza is a great jumper, too. In terms of qualities, I think Caro has amazing jumps!
