The G's styling is much more subdued. Its really a more mature, luxury-oriented ride. This is not something I wanted in a 300+hp vehicle. Yes, there's a certain value in having a sleeper on the streets...but that's not what I was looking for. While the G may have turned my head back when it was a G35...I find that the G37's body lines really don't do it for me. I like the Z's sexy hips and azz much more.
Also..there's something to be said for not having to be the one to haul your workmates around when it's time for lunch.
