stock the nsx is more fun to drive than the other cars. The turbo japanese cars have a much higher tuning potential, but stock the nsx is just more fun. The zo6 is also a good mention. I have respect for it, it is very quick afterall. But if i could have either, or had to drive either, I would take the NSX.
Gotta give the Z06 this one. Its beautiful to look at, handles incredibly, is pretty damned fast and is just overall a great car. Although as a cheap alternative to get you some massive V8 hp the SS camaro is pretty good. Too bad they didn't really do as much with the american cars as they could have, but we all know why.
I wrote the poll and i decided to keep the RGT out because i think it should be in a class of it's own... it costs 4 times more then about every car and its also faster then all of them, its like adding a Ferrari F-355 to a bunch of camrys and corollas.
