In a straight fight, Super Sonic clearly wins, but a couple of times in comics (and I guess technically in one of the games), Sonic has gone rounds with a Super and managed to not get beaten in one hit, usually hanging on long enough to still pull off some moves. Plus, in the games, he doesn't always really seem that much boosted from his baseline as Super Sonic. Even his ability to fly is inconsistent. I'm not that well versed on all the appearances, but this is more of a "how much of a boost is Super Sonic really?" thread, I guess.
