Re: Batman Vs. Superman... can this be a fair physical fight?
Im pretty sure Superman wins all early fights with Batman, hence why he was holding back so much and not taking it as serious, in The Dark Knight Returns, and hence Bruce's most final and desperate and menacing attempt, that nearly takes Superman's life.
And the pure joy and satisfaction, even in near death and in the midst of a heart attack, when Batman is telling Clark how he is the one man that actually beat him. His most triumphant victory. Bitter sweet ending it is, in The Dark Knight Returns.
