Who would win??

Kirk wouldn't stand a chance against Vader, once he chopped off a hand Kirk's only offence (the double axehandle) would be destroyed.
You are forgeting entirely about the sissor kick, as have many of Kirk's vanquished, much to their rueful dismay. Remember the climactic scene of Star Trek III : "...I...(stomp!)...have had...(stomp!!)...enough of you...(stomp!!!)..."
Wow, guess I earned my plastic ears with this pathetic geek post.
