Megaman SF has speed and power that would make the toughest of fighters mad with jealousy. While he is not quite as powerful as Megaman EXE, he outranks the other versions and that is no small feat considering how powerful Mega Man is. Gutsman would not be able to keep up with Megaman SF at all and he would be soundly defeated. His Guts Hammer would shatter in this fight. Megaman SF wins.
