I would say Revan/Darth Revan.
No Nur, not simply because he makes me feel like superman.
He would use his supreme tactical mind to work his way through the weakest opponent to the strongest opponent. he would form alliances with others to take on the strongest guy, (Exar Kun), and then betray them, striking them when they least expect it.
Revan would also find a way around Exar, removing him from his amulets etc, and either destroy them, or maybe use them for himself. If he was a former Jedi, then a Sith, he must have studied something on Sith history. Revan using those amulets is extremly unlikely, but I beleive Revan would win the day.
My idea, be gentle in destroying it.
