IM vs. Wonder Woman: Pure h2h
Ironman gets to pick his strongest suit except Hulkbuster. No weapons but he's allowed to use his thrusters.
Wonder Woman does not have any weapons though she does have her bracelets. No superspeed for WW and no energy attack from clanging her bracelets. She is allowed to fly or super jump.
As stated, this is pure h2h combat. Fight is in an open field. No bfr's. They don't know anything about each other, fight starts 50 feet from each other. Who wins?
