Well, i think the PT would win.
Basically Jedi can sense their opponents next move yeah? But logically OT Ob1 and Anakin have already had this deul when they were the PT version of themselves, so they know their opponents every move.
But if the OT won, then the PT wouldnt have been able to grow older and become the OT version so therefore the duel couldnt have taken place.
So PT much win.
