Anakin Skywalker & Ahsoka Tano vs. Asajj Ventress & Barriss Offee

Who would win in a battle to the death?!
Takes place on an open plain.
All characters are in their S5 incarnations.

I think this would be a very close match, a match that I honestly don't know who would win, though I'm leaning Anakin/Ahsoka. So, we all can agree Anakin>Ventress and Barriss>Ahsoka, but I think the fight between Offee and Tano was obviously rigged in Barriss' favor, and Ahsoka was disadvantaged from the start. Barriss obviously planned out her fight between her and Ahsoka, which is quite evident of how the fight played out. She lured Ahsoka around the entire warehouse to various locations, so that in the end, Ahsoka could be found near the nano-droids. Barriss had a massive environmental advantage. And Ahsoka was without her shoto, which she had become accustomed to using. In a even ground setting where there are no environmental advantages or disadvantages, Barriss and Ahsoka would be more closely matched. So their fight in this scenario would be longer and closer than their previous engagement. What are your thoughts on how this would play out?

Honestly I think the difference between Ahsoka with her shoto and not at an environmental disadvantage, and Barriss is less than the difference between Anakin and Ventress. I think Anakin would defeat Ventress before Ahsoka falls and then Barriss stand not even a sliver of a chance
