By looking at my Avatar and Signature, you can take an obvious assumption of who i voted for. The reason i did vote for the Count is because his timing of turning to the darkside was flawless, along with his respected relationships with all of the Senators.
I mean, he was a Political Masterminded AND a Sith lord that controlled a Separatist Army that killed thousands of clones and not to mention wiped out a fair amount of Gungans. (Now, c'mon, no one likes a Gungan.)
He was a master of the fighting art of Makashi/Form II/Way of the Ysalamir. He chopped the Chosen ones arm off. And Obi Wan Kenobi defeated General Grievous, who had four lightsabers, Darth Maul who had a double bladed saber (And Obi was a padawan when he beat the Sith Lord Darth Maul.) and he chopped the Chosen one up, but Count Dooku was always able to defeat him, AND throw a large metal platform on him that seemed to do no damage whatsoever.....
He also held his own against the legendary Jedi Master Yoda, who initially never really defeated the Count. Maybe the Count could have won against Yoda. But Count Dooku fled because he had the plans to the Death Star.
Count Dooku also was Master of Qui Gon Jinn when Dooku was an accomplished Jedi Master.
In my opinion, he is one of the greatest Sith Lords to roam the Galaxy.
