Dr. Strange will win because he is the most powerful Supreme soccer in marvel universe as well as he have infinity stone

Comeon the answer has got to be Dr Strange. As @MrUniversex7 said, that guy can handle an Infinity stone. Doom stands no chance.

Dr.Strange is the “Sorcerer Supreme “ he has power that ”Ancient One “ valued he’ll definitely win

Once dr. Doom was also been “sorcerer supreme” . So when magic and his intelligence of science combines than he could defeat dr. Strange easily.
