I chose the glossy 15" in "standard" definition.
I would have preferred the higher definition screen, but purchasing through Amazon saved me about $250, so that customization alone would have cost me ~$350, and I couldn't justify that cost.
For what it's worth, I'm very happy with my screen. 🙂 Good luck with your choice.
PS - Everyone has their preference, but I've noticed that much of the glare can be mitigated by using the screen's highest brightness setting (when needed).
