I have some ray bans I don't wear so much, and some randolph crew chiefs that I love but with were just slightly bigger.
For people considering buying the RE, if you follow their fit advice, you'll get something that fits your eye socket, which might be smaller then you expect, given most aviators are oversized. The crew chief only come in one size anyway.
I considered going for the concorde's, but I don't think the style suits me. I may get some aviators from them at some point.
The quality and looks in person significantly exceed ray ban (for less money as well). I was never unhappy with ray ban, but there's no way I'd get ray ban aviators over RE.
At some point I'd like to get persol's or similar.
