I agree that from the factory the Z06 is the fastest accelerating Corvette ever produced for the public. The ZR-1 still is the fastest top speed because the Z06 runs out of gear in 5th, and 6th does no good.
However, the Z06 wasn't built to be a drag racer. It's a road course car that happens to be powerful enough to be drag raced respectably.
The main reason I bought a Z06 is because I really appreciate a performance car, and if I'm going to buy one, I buy the best one I can. The base Corvette is a really nice sports car, but the Z06 is built strictly for performance. Alot of guys who have a regular C5 try to make it that the Z06 isn't that much different, but in fact it's alot different. And it's straight from Chevrolet, which I think is really cool that Chevrolet would build a car for hard-core performance minded people. But I'm saying it's not BETTER, it's just different. If you like a convertible you won't like the Z06 as much. If you like Magnetic Ride suspension and all the wiz-bang gizmos, then you won't like the Z06 as much as a coupe. But if performance is your top priority then the Z06 is for you.
That being said, my modded '97 Camaro is faster straight line acceleration-wise than my Z06, but the Z06 does the braking, turning, accelerating, over and over and over again, much better than my Camaro can even though I have aftermarket brakes and suspension on the Camaro. Plus the Z06 is just as comfortable as a regular C5 to drive to work.
But all Corvettes are cool. I really liked my 1995, And sometimes I wonder if I maybe shouldn't have traded it. Also one day I would like to get a 68-74 vette and fix it up, because I really like the shark style.

One last thing:
Unfortunately I found out by going to the car shows with my '95 and my Camaro that alot of Z06 guys are stuck up. :eyerole Big deal that your car is faster than a 'regular' Corvette or Camaro. As far as I'm concerned, if you didn't work on it yourself then it's nothing to brag about, because anyone can buy your same car. It's like paying someone else to modify your car for you then acting like you have something special. You don't. My grandmother can pay the same guy for the same work and have the same car.
uh oh...I'm starting to rant....
