Darth vader! every time! kilo ren couldn't even get a lightsaber out of the snow! not to mention the hair! holy cow!
neither are as good as campbell
Darth Vader of course would win. He is stronger in the force, not to mention that he is the chosen one. Kylo Ren is an average sith.
Darh Vader can use the force choke unless kilo has something better like the nights of ren but other than that Darth vader would win in a bttle
he has lit hair
kylo ren is simply better.
