Torque at any RPM, gear selector goes where you point it without hesitation, sounds like a million bucks and the KW does a lot of magic to the car. Just an all-around versatile performer whereas the GT3 requires a lot more concentration for every move you make. Not a bad thing but for street use, the RS4 wins. The GT3 is dialed-in for mostly track use and I quit going there years ago but still do canyon runs. Both great cars in their own different ways but if I had to keep one, it would not be the Porsche.
