Team Martian Manhunter Vs Team Xavier

MM

Manchester Black

Maxwell Lord

vs

Xavier

Emma Frost

Jean (No PF)

Since you didn't say it was TP only, they all set up telepathic blocks to resist one another and MM physically mops the floor with team Marvel.

I'm assuming this is TP only

Anyways, Team 1 wins. DC just has much more powerful telepaths than Marvel.
