The EVO VII is certainly faster, both in a straight line and round corners, however there's not much init, and you really need to be a very experianced driver to find the diffrence. The EVO uses some flash torque splitting between the frount the rear, so is much tighter in the corners, while the WRX is prone to suffering a little Understeer that just keeps building as you approch the limit.
The STi also seems to have developed a bit of turbo Lag, cetainly a lot more than the more flexiable EVO engine.
However the WRX wins hands down on everyday driveablity and comfort. The suspension is a lot more compliant than the EVO's, and still offers huge amounts of grip, the seats are also a lot more comfterble and bit wider, there designed with european bottoms in mind, not just japanese ones.
So if you want a fast car for blasting down deserted roads on weekends take the EVO, however if you need a daily driver as well, and like to be a little comfterble while stuck in traffic then take the WRX STi.

Personaly, I like the look of the EVO better than the WRX (which looks like a corrola on steroids.), as for which one I would choose? well give me the keys to both and ill try and make a desion. :sun:
