Knuckles in his base form one-shotting Hyper Sonic, a giant robot doing the same, etc. Meanwhile, none of that happens to Super Sonic.

Hyper Sonic also has no feats any higher than Island level. People place him at twice Super Sonic's power because the Archie Comics say that the Super Emeralds are stronger than the Chaos Emeralds--yet the games say nothing of the sort. Based on what we've seen, Hyper Sonic is weaker.
