I also had 2 S2000s before I bought my Evo. I was going to say the S2000, but I figured I'd get chewed out for it. From my experience, the S2000 has more potential in the hands of a competent driver. The difference is that it takes a VERY talented driver to take the S2000 to the limit (the best way I can describe it is that the car is literally trying to murder you). The Evo can be driven stupid fast by even a very incompetent person. I've autocrossed both cars, tracked both cars, and I've driven both cars up at the Dragon more times than I can count. The S2000 is a momentum car. The Evo is big and heavy and only handles the way it does because it is robocar. The S2000 handles better, from a purists point of view, anyway.
