^ Yikes, you got supershadow'd. Those Midiclorin counts are from his site!
Anyway, if they fought in ROTS Yoda would win, but are you talking about if Vader had never got injured and reached his full potential could he beat Yoda? Cause if that's the case GL said that Anakin/Vader's full potential (if he hadn't sustained the injuries in ROTS) is twice as much as Sidious's.
So you talking full potential Vader, or ROTS Vader?
