steve has taken on so many guys outside his weight class, it's rarely surprising when he does things like this--but yeah, the whole tearing apart tony's (superior) armor like it was tissue paper was a little 😑
as for this fight: the h2h one would be a lot closer than i'm hearing. flight would help, obviously, but i'd say pete is stronger and strong enough to do damage to the armor if all tony can do is punch him. not sure who the majority would go to, but i think i'd favor pete slightly in the h2h.
no flight but full weapons for tony would almost certainly go to tony every time. he's close if it gets in h2h already. weaponry would def push him above pete by a decent margin.
