I must say, I haven't noticed this either and I've been reading religiously every day for the past six months.
But if there is a consistent negative undertone that I've missed, then OP, don't even let it bother you man. You have an amazing car that you're proud of, right? That's the main FACT. You prefer the model you got and you're fortunate enough to be able to afford it. If there is a disproportionate number of Nismo flamers, let them be. Much of it could be underlying jealousy/envy, anyway. But you love your car and that's all that matters.
'Haters gonna hate', I believe is one of the 10 Commandments.
Me personally, not to be intentionally ironic, prefer the curves of the front and rear spoiler and the Rays wheels of the sport pkg over the squarer, more aggressive-looking Nismo body and the Nismo wheels, so I went for that. Plus I was concerned of reviews claiming the suspension was a little too stiff and uncomfortable for a daily driver (your thoughts on that?). But it's each to their own. I love seeing Nismos around - hope to drive one at some point for comparison.
