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.
But the Martian Manhunter can also go immaterial. The example that springs to mind is in "Divided We Fall" when he does so to try to escape from a hoard of demons.

Well, Vision can emit a beam of infrared or microwave radiation from the solar cell on his head. MM, as far as I'm aware, can't project any kind of energy. And as a machine with artifical intelligence, the Vision might be smarter than MM.
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.
(Shrugs) Plastic Man called it "going ghost." I hardly think it's important.
