I don't know much about Aayla, but here's what I know about everyone else.
Quinlan: Strong Jedi, killed Sora Bulq, who was a legendary lightsaber instructor turned ark.
Assaj: Wannabe Sith, with strong dueling skills. She defeated Kit Fisto and killed many other Jedi Masters. Beat by post-AOTC Anakin.
AOTC Anakin: Mediocre duelist, beaten by Dooku, who was arguably strong enough to hold off Yoda for some time.
Now, let's look at the possibilities..
Scenario A:
Quinlan vs. Ventress = Ventress
Aayla Secura vs. AOTC Anakin = Anakin
Team 2 Wins.
Scenario B:
Quinlan vs. Anakin = Quinlan
Aayla vs. Ventress = Ventress
Quinlan vs. Ventress = Ventress
Team 2 Wins.
That's what I think at least.
Okay, If iot was Aayla from TPM she is still a Padawan and Anakin could beat her, while Asajj could beat Quinlin. But if it was ROTS version, she's a Knight (I think, maybe a master, not positive) and between AOTC and ROTS she defeats Aurra Sing. So if it's AOTC or ROTS ayla she'd beat Anakin but Quinlin would still lose to Asajj and then Aayla and Asajj would fight and it'd be close but Asajj would win. So I guess it's team 2 no matter what episode Aayla's from.
Assaj would wreck Aayla, and defeat Quinlan, although not as easily. I'd say she alone could pull it off, considering her past duels. She would have killed Obi-Wan Kenobi in the Cestus Deception if it weren't for Kit's interference.
Now, Anakin by AOTC is no mediocre duelist. He's good. he has Dooku hard-pressed for a moment, although the Sith Lord had no chance of losing, of course. He's pretty good, and probably capable of taking out Aayla, ROTS or not.
