Well, this should be decently close. Metal Mario replied to my comment on his Mario and Luigi VS Sonic and Tails Rematch blog, so I have some info for both. Well, both of the top tiers are around Universe level+ at their peak (Mario, Geno, Peach, Mallow, and Bowser being able to harm Culex; Super Sonic, Super Shadow, and Super Silver fighting Solaris [note: apparently Solaris' defenses were pierced by Super Shadow's Chaos Arrow]), since there are no Paper Mario and Archie Sonic characters.

The difference is though, that Mario and co. fought Culex in BASE form, while it took Sonic and his allies in their Super forms to defeat Solaris and Time Eater. With their strongest powerups, Mario, Luigi, and Bowser would probably be Multi-Universal. And if Dreamy Bowser is included, the Sonic-verse is doomed, even with Solaris. Plus, you could argue that Mario and Luigi are Multi-Universal to Multiversal from fighting Dreamy Bowser (I'm a little skeptical about scaling them too him since Bowser in base can still survive hits from Mario and Luigi yet he lost even as Dreamy Bowser too them, although it is possible you could scale them).

It's a close fight, but the Mario-verse takes it. However, include Dreamy Bowser, and its a stomp in favor of the Mario-verse.
