LOL G37 and RX-8 can barely be compared at all, the G37 is more of a luxury sports car than the RX-8, and it also depends on what you likd more, the cool gadgets and higher torque from the G37? or the high pitch whine of the rotary engine from the 8 xD

personally i like the 8 more but i do see that the G37 is a nice car too =)
one of the major downsides of the G37 is that your car doesn't turn heads when you drive to stop on stop lights =)

congratz on the purchase =)
