Nah, Prof Hulk would have definately lost to Maestro without too much question (and its not like Prof Hulk is weak mind you). That Hulk almost cut Maestro in half with Caps shield, and Maestro still had the strength to knock Prof away and regenerate from the attack. Im not saying Rulk couldnt do the same thing, but Maestro is definately a level above Prof Hulk to me.
