If you're going for half mile domination then the Venom GT is easiest to win with. Once you have the tuning package the Aero TT becomes EXTREMELY competitive with the Venom. I had someone run a 10.957 with an Aero TT on me in the half mile yesterday, and as it is my own Aero TT runs 11.06X. I have seen someone run a 10.947 with the Venom though.
In the quarter mile, the Venom GT is extremely competitive too. I have a feeling though that if you tune it right, the Bugatti SS would be unstoppable - with it's ridiculous amount of grip.
