Glossy or Non-reflective Screen

Anyone here used both the anti-glare (older more common) Laptop Screen and the new optional glossy laptop screen you can get as an option on the MacBook Pros for photo editing?

I was looking at both today and indeed the glossy screen does seem have a bit more umph, contrast, saturation.

However, I am paranoid about the screen glare.

Does anyone know if one or the other has a better color-gamut? I have profiling hardware just wondering if one screen or the other has a better range to work with?

I know both screens are much brighter then the old G4 powerbooks, but would the glossy screen or the anti-glare screen be better in a bright enviroment? Outside?

Thanks.
