No one. They both stay intangible, afraid to make the first move.
They both flew at and through each other, during a canon Marve/DC crosover, and they both screamed out in pain.
If I had to pick one, it would be MM. He has better overall "stats" than the Vision.
He cab go "supernova" though that still screams hyperbole, even still he can project fire from his diamond and "cells".*
