If the Vision wanted to win,,,,he could. The Vision loses battles because he attempts to battle foes with his sheer might. I never understood why he would want to go toe to toe with an opponent when all he had to do was stand there in his intangible state until he could put his hand inside of them and turn somewhat tangible. Seems pretty easy.
MM can also somekind of blasts from his eyes. They are about as strong as Supermans heat vision. He also has super-strength,(about same as superman), super-speed,(about same as superman), he can fly, he can transform to anyform he can imagine and he has telepathy. But seeing as Batman took out four these kinds of things with canister of gasoline and one match, I think that Vision could have hopes beating him.
