Honestly?
Despite it's flaws, Bubsy: Claws Encounter of the Furred Kind is probably the strongest argument for the SNES up against Sonic's claim of "blast processing".
What I mean is, it proved that the SNES, without any additional chips or anything required for the later graphical improvements, could run a game exemplifying the same Sonic speed and action as the Genesis, despite Sega's claims otherwise.
Like- Bubsy's problem was level design. Functionally, it runs as good as Sonic 1. And at times Bubsy runs faster than Sonic in Sonic 2. And graphics stay fairly smooth. It actually proved the SNES could compete in a way that most other games failed to show.
Most Sonic clones with Sonic-esque gameplay either fail to show the SNES's capabilities because they shy away from Sonic-style gameplay or they were Genesis exclusives.
But Bubsy showed that while the game wasn't great, the SNES was capable
