So nobody thinks team 1 has a shot? I feel like Dooku vs Sidious would be fairly close in a sabers only bout. They each performed rather similarly against Yoda in the saber portion of their fights (Sids lasted a bit longer but unlike Dooku, Yoda was able to disarm him).
Now, if we were to say they could use force speed to enhance their fighting ability then Sidious would speed blitz a la the arrest scene. But in terms of pure saber skill/instinct/prowess it'd be close.
Same with Anakin and Obi-Wan, though the former would probably have the upper hand when fighting with a clear mind.
Feats say Anakin becoming Vader was a major drop in power for him.
Dooku is a far better duelist then Kenobi will ever be. Anakin whooped him one. Then, Vader turns around and gets his famous Mustafar injuries from Kenobi.
Hence:
ROTS Anakin>Dooku>Kenobi>ROTS Vader
Now, by ROTJ, Vader beats his ROTS Anakin self, because he's that much more experienced, but in ROTS, being Vader just handicaps him.
And so, Anakin would stomp his evil self.
