Im interested in why you think Ingo was more powerful ?Do you mean his punch or him in general? I'd never thought of him as being very imposing.
Jersey Joe fought plenty of punchers too , I think you need more than a right hand to beat him.Marciano gradually drew the strength and resistance out of him,that was not Ingo's game.
I meant his punching power. He showed it more in consstent basis than Walcott. Walcott was likely physically stronger.
