I think Saitama is stronger. His power is seemingly limitless and he has never struggled in a fight. Goku, although powerful, has had many intense battles where he was pushed to his limits.
In general, it's a bit of a toss-up. The strength of Manga Goku and Anime Goku can vary depending on the specific arcs and battles. Sometimes, it might seem like one is stronger in a particular situation, but that could change in another.
It's a bit hard to say for sure. Both Vegeta and Goku have their moments of strength. Goku has some unique powers and techniques that give him an edge at times, but Vegeta is no slouch either and constantly works to catch up and surpass Goku.
In my opinion, it's highly unlikely. Goku has mastered multiple forms and techniques that give him a wide range of powers. Saitama's one-punch style might not be effective against Goku's diverse skills and battle experience.
It's really hard to say. Saitama has shown that he can defeat any opponent with a single punch. But Kenshiro is also extremely powerful in his own right, with his martial arts skills. However, if we consider Saitama's ability to break any limit, he might be stronger in a direct confrontation.
It's hard to say. Adult Goku has more experience and has achieved higher power levels. But Kid Goku has an unbridled potential that could make him a formidable opponent even to his adult self.
I don't think there's a clear winner. Both Manga Goku and Manga Saitama have unique and powerful abilities. It could come down to strategy, luck, or even the author's imagination!
