The GT-ONE may look a load of ****, but if u ask me, it is definately in with the best on performance. I myself dont own the R390 as of yet, I havent tried for it, but ive tried the one in the arcade mode, and if it can keep up with, and beat an 800 HP GT-R, not a special, then it claims a high position in my eyes. The handling is sweet too, just takes the corners, no matter what the angle. Brilliant, wait till i get mine.
I notice nobody has mentioned the Zonda Race Car !!! I can't believe nobody has mentioned it, either not many people have it, or they dont rate it like I do. AS withe u said the top three (midus gt), the 787B, the GT-ONE, and the R390, I think that the Zonda race car is in there too. IT handles sweet, and had a massive top speed, acceleration aint bad either, well, what more could you want for over 1080 BHP ???
