Well, it's not that obvious for me that Luke is > Ben. Vader had an incredible ammount of hate for Obi-Wan, while he could be conflicted against Luke.
Indeed, is seems that Luke was winning against Vader, even before his rage assault, but well... Ben stomped Maul and gave Vader almost an equal fight. Rebels Ahsoka was about equal to Maul and was going to be beaten by Vader.
Anyway, Anakin should be a strongest one here and his team should take a small majority.
