My MacBook Pro is antiglare -- I like both displays in their own respects for different applications. I think the colors on the glossy might be a bit more vibrant and the display might appear brighter in some regard, but in any kind of bright light the GLARE is horrible. The antiglare is nice for working with photos and general use, but it's only offered as a high-resolution option on the 15" -- if you like larger more visible GUI elements and have eyes that are "not so good", then the only low-res option offered is the glossy on the 15-inch.
The new glossy displays are not bad, all of them are good I think, and it's usually a tough call when buying. Most people also do not have the option to see a high-res glossy 15" in the Apple Stores when they buy, because they do not offer them in-store.
I do a lot of color grading, and work with cinema 4d, photoshop, after effects, etc and I perfer a glossy screen. The matte option may not be reflective, but it's ugly as hell. The colors look better with the glossy. And I like the black bezel.
