I tossed Vader a vote
I like Vader, Fett and Palpatine. In many ways none of them ahve been fully developed characters until the prequels filled in origin plots. Vader is the most rounded character. Fett's always been more of a theme, but still a fave.
It's nice to see recent EU work tie things together for him. Palpatine has just had minimal exposure, but I like him a lot based on the movies. Even after Ep. III.
