Who jumps the highest at sonic riders

Presuming you didn't notice, Sonic runs as fast as every other character in the game. For example, Storm runs as fast as Tails, who is as fast as Knuckles, as Jet, Wave, Sonic, Shadow, Amy, on and on and on. The same applies in everything. The only difference a character makes in gameplay is what their basic move is (Sonic=Speed=grinding).
