They may seem like the same thing, but really, they aren't. It's like when a sports announcer says New York didn't win, Washington lost. What he means is Washington was the better team, they just made a critical mistake that cost them the game. So my question is this: Was Anakin the better swordsman who just made a critical mistake or was Obi-Wan the better swordsman all along who was just trying to talk Anakin back from the Dark Side? I think Obi-Wan won. He could have taken Anakin at any time, he was just drawing out the fight hoping his "brother" would come back to the light.
