Might as well get my vote in too. I'm going with Smurph/Existere. Overall I feel he presented his case better, and I really couldn't see Mags doing as well against Surfer as Cable did.
Although Leo exposed the folly of some of the tp arguments Smurph was making, it was still impressive for Emma's shields to be barely holding against Cable's passive tp field, even without Cerebra. Sure, Magneto can block Emma's tp but IMO that's not as impressive as her struggling to keep his tp field out when it was affecting the whole world at once and not even concentrated on her.
Also part of Erik's tp defense comes from his helmet which Cable would probably be able to destroy/remove with his powers, thus making the tp assault easier. I also agree with the part about Cable having finer control over his tk and matter manipulation.
It would be a good fight but in the end I think Cable wins.
