Who would win in a fight Spider-Man or ironman?

Actually im not sure about this but in the spiderman what if comic where Mary Jane gt shot instead of aunt may it shows peter just simply destroying the armour by finding a fault in the suit it totally fell apart and one punch and tony was out that was it so i think spiderman would win but im not sure because i don't read iron man comics and don't know about the extremis armour

I think spider man. He could probably bust up the armor. When theres theres no Iron left all ya got is a man.
They fight in the civil war and it went either way. there pretty equal
