Well I hadn't driven an MS3 until after I drove the X GSR, and your probably right about just getting used to the way the clutch lets out on that car. My impression of the car is majorly based off my 20 min test drive, but I honestly was dissapointed in the entire feel of the car, especially haven driven an '06 MR.
I don't doubt a modded Evo X would be (better) around a track than most cars made; however to say its a better car all around- not in my personal opinion. I would rather drive an AWD MS3 for sure. I do really like STI's and Evos, but would always rather spend the extra dough modding an MS3. Imagine this- buying that awd ms3 for $25k and using the extra $5k you would save from buying an Evo, to get 350 whp out of the MS3. It wouldn't be like an 11sec Evo, but I bet It would be more fun.
May I ask- why did you go from an Evo X to a Speed3, if you thought the Evo was a better car? Better car is a hard statement to make- I used to own a Corvette C5, Jaguar XJR, and a Trans Am, all of which I loved dearly. None of them broke as much as my MS3, and all three got a lot more compliments and attention, but I couldn't say any of them are actually better than an MS3- just DIFFERENT.
