Who do you think would win in a battle between Ser Arthur Dayne the Sword of the Morning or Luke Skywalker in his prime (Legends not canon) were gonna assume that Luke's using something that doesn't just cut through steel cause it wouldn't be fair and that he doesn't use the force cause ya know it gives him an unfair advantage and that this fight is just skill with a blade.
Ser Arthur Dayne: in case you haven't heard of him yet.
