Iron Man also have the Colossus muscley going on, plus the blastyness of Havok, inventiveness of Forge, Adaptability of Lifeguard, and intelligence of Sage.
Most Avengers are worth several X-Men. Hercules, Wonder Man, Thor, Photon, Blue Marvel, She-Hulk and Sentry are OOC problems for most X-Men teams. They could pretty much handle most of the bigger badder X-Villains the whole team usually has trouble with like Apocalypse or Sinister.
