Doom's edge
Walker's strength is enhanced, not godlike, and Doom fights from the air and out of reach. Doom beats Steve Rogers 78% of the time on this site; Walker is stronger than Steve but a lesser tactician.
U.S. Agent's edge
Enhanced strength and durability from the Power Broker, government training as Captain America, a shield, and a temper that never lets him back down.
