Master Chief's armor may have a limit, but it's far more powerful than Cap's body armor AND has a recharging shield; considering what it can withstand in the games, I doubt Captain America can do much with a pistol and shield. In addition, the Chief is naturally faster and stronger than a normal human being, and his armor actually increases those attributes, so I highly doubt Cap is more mobile and agile, even with his skills.
