I looked at the nismo and prefer the sport looks. For what I do with it, the performance difference (what little there is) doesn't matter. I'm not a car guy, but I love cars. Not sure if that counts or if I just proved an earlier point.
Either way, the choice is definitely first world problems. Kind of like did you buy a Patek Phillipe or an Omega watch? Both of them are great, but one is obviously better... right? (or so the price tags tell us) Did you sign your sales contract with a Montblanc or a Parker? Montblanc's definitely perform and look better...
