Not sure about the 330i but Ive driven both the 325 & 328i, both with MTX. I have no doubt SVT is quicker (and in point of fact I have done in a 328i on the highway). They are excellent cars, more solid, beautifully crafted, but not more FUN. SVT has a high reving nature/more urgent, makes better sounds, and seems lighter on its feet. It's still a treat to drive. Thats all I'm saying...
