If you are intending to use a matte display for your viewing, i would say the Apples anti glare option is the only way to go.
The anti glare film application produces a grainy effect on the colors especially white. The colors and sharpness is not as good as the Apple's default anti glare screen.
The mbp anti glare screen option have better image quality compare to the film option. If you can adjust yourself with the lights, the glossy ones is good too without having to apply film.
The results of the apple's anti glare and glossy ones are very close results with each other in terms of image quality (colors and sharpness). So, get the apple's anti glare than the film option. on a side note, apple's anti glare screen comes with a silver bezel around it where some people dont like it at all. As for me, i have both the glossy ones and the anti glare ones, i prefer the silver bezel over the black bezel on the glossy ones 😛
Hope it helps...
