Borla vs Invidia vs Stillen

I own a 2010 40th Anniversary that is my little garage queen. It has around 3,300 miles on it. Prior to owning it, I had a 2007 G35 Coupe that was my daily driver. Ever since trading to the Z, I have always felt the exhaust was well below sub-par for the vehicle. I even at times think, how is it the G35 had a sportier and more aggressive sound to it than my Z? Well, I have been debating on upgrading the exhaust, but will say I feel very overwhelmed on the variety of options. Before even researching I thought getting the NISMO exhaust would be the way to go just to keep the fit and finish OEM. But it sounds like to many this is a very pricey upgrade for barely any enhancement. After looking through and hearing many videos, I have narrowed it down to three (but am open to change). I was curious, from those who have heard these, can you rate them 1 (being best, loudest or deepest), 2 and 3 in for the following items? I unfortunately live in an area that doesn't have many Z owners to personally listen to the options.
