User blog comment:So-Pro Warrior/Captain America vs Master Chief/@comment-4248317-20111205062152

Master Chief takes this easily. He has fought far tougher opponents than Captain America, he is faster, stronger, and smarter than a regular human, and his suit not only grants him superior protection, but it enhances his speed, reflexes, ect. even farther.

A couple of things though; in personal opinion, I think Chief should have the Physicality and Defense X-factors. Physicality, because the Chief trained almost his entire life under conditions that would kill most people, and in addition to that, has been biogenetically enhanced with methods/technology hundreds of years ahead of what Captain America had advailable (and CA's powers were given with one experiment), and Defense, because his armor covers his entire body, unlike CA's shield, and is much harder to disarm him of.
