This is a debate thats been on for years. I've driven both and they are very nice cars. They have there strong and weak points. Often one is better than the other because the drivers driving style suits his preference. The supra driven correctly can take out an R34 in a straight drag but when you see that corner coming up REALLY FAST you start to pray for the 4 wheel drive skyline. it also depends what modifications have been made to the cars and how they are set up ect.
