Episode 3 Obi-Wan manages to survive against both General Grievous and Darth Vader. General Grievous was the best hand to hand warrior that ever faced off against the Jedi, until Darth Vader. (IMHO) Yet, Obi-Wan defeated both of them.
However, Luke defeated the Mechanical Vader. (I argue is the more powerful Vader, as he has had many more years to master the darkside. His hatred for his wounds have fueled him into an efficient warrior and he was the head of the Jedi purge.) Now, While that is only one opponent, consider Luke's lack of training. He had maybe a few weeks at most with Obi-Wan, and not more than a few months with Yoda. I hardly doubt he had a full year's worth of Jedi training. Yet, with the force as his ally, he defeated the terrifying Darth Vader, argueably one of the most powerful Sith ever.
So I ask, who would win in a battle, EP3 Obi-Wan, or EP6 Luke?
