All Might is the symbol of Peace and you have to be incredibly powerful to live up to such a title. All Might never faltered in this role and shows that true peace was possible. Kyp is a reasonable fighter in his own right but we’ve seen some small instances of All Might around his peak and it’s insan. A single punch would absolutely take Kyp down and the young man won’t be getting up from such a hit. All Might wins.
