When you're 6' 4" anything will appear to be a high gorge to the average person. That said, I prefer a high gorge to a low one and when I see men in suits with the latter I immediately think, "dated suit". A higher gorge will always look sharper than a lower one. Screw fads.
That what people say about all fads. I'm 6'4" too and too high notches just make you look even taller.
