For me it's always been ESB Fett. ESB my favourite of all the SW movies for a start and I prefer the uniform color of his jp, gaunts etc. I know a lot of people cite that as a reason not to like the ESB Fett but I've never been keen on the color mish-mash that makes up the ROTJ Fett. Plus I like the lack of spats, the addition of a sidearm and the ESB flamethrower is just awesome. Love all the intricate parts it has.Finally I prefer the detailing and paint style of the ESB. The kill stripes fading from yellow to orange, the bluish hue on the right chest piece, the decals on the ear, the white dot on the jp, the orange stripe on the cape and so on.Just my opinion, I know there are many ROTJ/SE lovers out there too.
