The performance car is definately the TSX. We drove Accords and TSX back to back when shopping. The chassis of the TSX is simply brilliant. The steering responce is simply a joy, even driving to McDonalds will put a smile on your face. The Accord is numb by comparison.
And my favorite TSX feature isn't found on the Accord, HID's standard. Add to the list the sport-shift tranny if you need to buy an Auto and the TSX becomes a slam dunk.
