Nate Grey (full potential) vs Franklin Richards(full potential)

Ok, who wins this supposed battle, each at the height of their potential abilities? Also, WHY and HOW would the winner prevail...? This is a serious one folks, so fire up your bongs and meditate on it.

I am afraid that Franklin wins, hands down. I can't recall Nate ever creating a pocket universe in a simple rubber ball. If the kid has that much power, Nate is toast.

Oh, as to How. Easy, put Nate in a pocket universe then make it cease to exist.
