ESB Vader vs. Serra Keto and Cin Drallig

I was gonna put ROTJ Vader but as I doubt either Vader could do this I decided to put ESB Vader here instead to give him a slightly better chance. Fight takes place:
1. In Jedi Temple
2. In Cloud City Reactor Chamber

Remember, RODV Vader took on two Jedi Knights at the same time and defeated them with relative ease, and ESB Vader is even stronger but Cin is the lightsaber master and Serra Keto is his strongest student, and far beyond her years.

Who wins?

I say the duo wins, like I said, Cin's very strong and alone could probably put up a good fight. And Serra is very strong, at least as strong as the avg. Master, I'd say. They take Vader.

He can take either one of them, but they're a formidable team. I say they win.
