Luxury wise, i have the touring package and I prefer the Z's seats. The only things I miss from the G are the navigation (which is very well integrated into the car IMO), the backseats once in a while, and the slightly smaller steering wheel. The Z's wheel feels like its an inch or two larger in diameter. Leather quality is definitely better on the G37, but I prefer the suede inserts on the Z.

In my mind, the real advantage a G37 has is having 4 seats. Whether that convenience is worth the slight dulling in driving experience is more of a personal preference.
