i'd recommend u buy the evo. i've never driven an evo 9 but i own an evo6TME as well and all i can say is evos are just.. awesome! ive been to the track on the evo 6 and i noticed that its pretty easy to let the back step out a little bit and have a really good control oversteer. but, no matter what people say, i think that evo has the best go-kart-like handling compare with STI. plus, evos doesnt sound as gay as the boxer sound at high revs!
