Just don't forget the gt4, it was not as popular in the us. But a 3sgte modded and paired with an all wheel drivetrain is a force not to be messed. But it is hard to compare the supra to a celica. And really any two cars for that fact. Any car can be fast its just how much money you have to spend. After all you can put a mustang v8 in a miata.
Here is a nice video i found of the gt4 :
