the lamborgini is cooler, but thats only because its only owned by celebrities
if you were to actually buy one of them, go with the corvette, rear wheel drive is always better than all wheel drive (for burnouts)
the corvette is better overall, better reliability, go for the z51 package or the magnetic ride control and you can probably out handle a lambo, and the regular corvette can run a 4.1 0-60 all for about a quarter the price of the lambo
plus its american, no car is more american than a Chevrolet Corvette
