I just bought an Anti-glare 15" mbp. I have alreday had the glossy 15" mbp. Final result: Glossy (black bezel) looks better. Anti-glare (silver) works better. I cannot deal with the glare on the glossy screen, I couldn't focus, I couldn't play a game without second guessing what I was seeing, it just sucks. Besides that, the glass on the top of the glossy screen makes it heavier and when tilted to a certain angle(90 degrees or less), the lid just closes.Anti-glare is the ONLY option for me from now on.
So just for looks: black bezel
