I don't know about that. LM created one universe. Doc Solar not only created a universe(valiant), but a multiverse....two of them(acclaim.). The second when he used 10percent of his power in a fight....just that usage of that 10 percent accidently created a MV. He also created himself. But LM is the only calibre of character who could beat him. Feat wise, LM is outclassed. But it's not all bout feats.
When he took control of the creation energy and created everything in his own image, he in effect defeated god and became god. He was god of the entire acclaim reality. That's the closest thing to a TOAA in those comics. The one vulnerability he's got is mental. LM can definately take advantage of that. CIS on, LM wins.
