How differently do you think this fight would’ve gone if Tony had one of his allies with him?

The whole fight was sort of unfair, Tony was on his own while he was being teamed up by Cap and Bucky, even though it’s speculated Iron Man could’ve beaten the both of them if he actually wanted to hurt cap, the fight is still unbalanced.

Just wondering, how different would the fight go if it was balanced, if Tony had one of his allies with him? Spiderman, Vision, War Machine, anyone of them.
