Well, if you look at the majority, many who have started with glossy, swapped for anti-glare after looking at both displays at apple, not many have done the other way around. I think ideally, if time is not an issue, is to get a glossy, try it out... then if you want no reflection, then return for AG is the safest bet.
Sharpness on the 2011 macbook pro AG looks no different than the glossy. Only difference may be in slight color differences such as the blackness of the text and pop outness.
The way I thought about it is, if I were watching a movie with others and didnt want to turn all the lights out, but have others be able to watch it on my pro at different viewing angles with no glare... AG would have been the better social option for that as well. I have no idea how big of a difference AG would be compared to glossy in pitch blackness, but AG will definitely be brighter than the glossy, despite slight differences in saturation.
