PT in my opinion. I have no idea if ROTS Sidious is better then his ROTS self. His knowledge might be a bit deeper, but his body is weaker at that point. I guess his chances against Yoda are still about 50/50.
Vader is a great force user and another - next to Sidious a solid point of his team. But I don't see him winning majority against Mace or Dooku. He may be a superior Force user, but he's not far above them. In that way, it will be decided by lightsaber duel mostly. And I consider both Dooku and Windu as his superiors as duelists. Even Maul is a bit above him in that department.
Kenobi and Luke are inferior to everyone in PT team.
An argument can be made for either side.
But I think team 2 takes a majority.
Vader is superior to Mace in power, durability, and TK- they're even in speed and Mace is more skilled. Vaapad isn't helping him against him and Vader can take him while the Emperor blitzes and kills Tyranus and Maul
Even if you don't subscribe to the notion of the Emperor's speed, Luke is at least as fast as Maul and can hold his own against him for a bit.
Team 2 should take this 6-7/10
On neutral ground Yoda would be able to hold his own versus DE Sidious, for a time at least. So RotJ Sids shouldn't really be an issue.
Dooku and Maul will beat Luke and Ben more often than not.
Mace has shatterpoint which may disable Vader, not to mention vapaad.
And like I said, at worst Yoda and Sidious kill each other.
I'm going with Team 1.
