I'd probably say Super Sonic. While both are on a time limit, Sonic can, in theory, extend his indefinitely as long as he can get some rings. The only way Mario's resetting his timer is if he finds another star. Even if neither can extend their time, I'm pretty sure draining 50 rings (I THINK you need 50 rings to transform into Super Sonic, at least in most games) would take a lot longer than it would take for the Super Star jingle to play out.

Sonic just needs to wait about 5-10 seconds and then kick Mario in the nuts. GG.

Of course, if we're assuming they can hold these forms indefinitely, then that's a completely separate question... and I'm honestly not sure what the answer would be to that.
