I would pick the 911 because I like it more, but the Corvette is clearly the faster car.

Scratch that... If I'm spending 100k on a sports car, i'd get a TVR or something more exotic than either unless I'm rich and I'd buy both.

ZR1 all day long.

Why?

I have driven a C6 and that alone was a wonderful car, I just love they way they drive, and all the power to boot. So I can imagine that the ZR1 is even better with a supposedly more sought out suspension etc, and I would love to see the Porsche owners face when he sees the 4 round brake lights disappear into the horizon.

GT3 4 me.

GT3. I would expect it to be more tactile, it's better looking, and it's still way more than I could handle. I would expect it to also be much more fun to drive, overall, despite the power disparity.

The ZR1 is way faster but it's also way out of my driving skill league. I think I'd have more fun with the Porsche.

Neither. I don't have $100K to drop on a car.

Even if I did, I probably still can't answer your question. I haven't driven either one of them, so I don't know which one would suit my tastes better. However, if I had to buy one just on my perception of them, I'd take the Porsche just because I've always wanted a Porsche. The ZR1 doesn't appeal to me any more than a Z06 or even a modded base Vette, so I couldn't justify buying one over the lower models. However, the GT3 does appeal to me much more than a basic 911 or even a 911S.

So, I guess my answer would probably be GT3.

Porsche all day. Nothing can seriously compare. If you drive a Porsche extensively, then you will know what I mean. I mean I drove a measely 996 (non turbo) for a year and even that car convinced me that Porsche is amazing.

ZR1. The looks of the c6 Corvette blow away anything but the Porsche Carrera GT.

GT3, mostly because of I owned the last-gen Z06. Chevy still has a bad taste for me. Plus the GT3 just comes across as more exotic even to my eye, fair or not. I'm an enthusiast and the ZR1 visual difference is still mild. The general public will see it a riced-out vette if they see any difference at all. That same general public will also see a riced-out 911 in the GT3 but the base 911 is, what, more than double the value of a base vette?

Some visual reference :D
