I go for team 1. I agree ahsoka at the level she left the temple couldn't defeat ventress or Barris, so she would be defeated. So that does leave obi wan vs fisto, kolar, and tinn while anakin fights Windu. I'd go with anakin, as he is a better duelist than Windu and he's regarded as a 9/10 by the stunt coordinator up there with Sidious.
Windu >/= Anakin
Kit Fisto = Obi-Wan Kenobi
Seasee Tiin or Agen Kolar > Ahsoka Tano.
One of either Tiin or Kolar is free to assist Windu or Fisto here.
B team wins.
Wait.... Agent Kolar? Agent Kolar solo godstomps and the sheer strength of his godstomp tears through the fabric of space to kill Vitiate, Kun, Sidious, Caedus, and Abeloth.
He is then elected Grand Master, Master of the Order, Weapons Master, Battlemaster, Historian and Barsen'thor. Then he proceeds to get in bed with Aayla Secura, Shaak Ti, Ventress, Padme, Leia, Jaesa, Vette and Scarlett Johannson.
Why do people think Obi-Wan increased exponentially during the Clone Wars while Fisto sat on his ass eating cheese? During the Cestus deception, Kit Fisto was his noticeable superior, while purposefully hampering his own speed (the thing that actually allows him to compete in dueling.)
Even if Obi-Wan increased that much and Kit sat on his arse for three years, it would be a close fight.
So what? We're just supposed to pretend Fisto improved to ROTS Kenobi's level with Zero feats to place him there?
That's like saying Anakin was no match for Dooku in AOTC therefore he was no match for him in ROTS, because Dooku wasn't just sitting on his ass for 3 years while Anakin was improving.
Also Fisto apparently being Kenobi's superior in Cestus Deception means very little considering Fisto got solidly beaten by Ventress in that same novel. Then not long after Kenobi solidly beat Ventress in TCW Movie.
Kenobi's feats are way above Fisto's. That's why he's placed firmly higher.
