I don't think something like that can be answered. Lancelot has beaten Arthur, but not with a sword, at least not without tricking him, but Arthur has beaten Lancelot. Morgause and Morgana beat him in the past too. I don't really think Arthur is THE best, maybe one of the best swordsmen/women out there. So I guess I'd say Morgana or Gwaine, because they fight in a unique way with a sword.
