I just went through this very quandary. Last week I owned a total of three MacBook Pros, first the AG, next the standard glass, and then the AG again.
I can say definitively that I prefer the color balance and everything about the AG. That's the summary.
Why I went through three? I got the AG home and thought the res was a little too much to handle, so I took it back to the Apple Store and exchanged it for a standard res glass. Res was much easier on my eyes, but at the same time I just couldn't get comfortable with the over saturation. I'm a bit picky when it comes to colors and monitors, for example I almost can't stand my HP EliteBook that I use for consulting work as regardless of what I do the panel has a heavy blue balance to it. It drives me crazy, but it's better than most, so I live with it.
Getting back to it, I had the glass MBP for three days and just couldn't get over that, or the reflections. The latter were mostly minor, and I was actually surprised because I've had a late-2009 white MacBook since, well, late 2009 and I've never noticed it. Yet side by side it's pretty clear, that glass really reflects. And it also is heavily saturated, even when compared to my white MacBook. I was able to fiddle with the calibration and get it more neutral, but frankly I missed the natural color "pop" of the antiglare.
In summary, my eyes prefer the antiglare MBP. They also really dig the late-2009 white MacBook, and honestly the panels on the 13in MBP's look quite nice as well.
I'd take some time to compare the two, and see which yours prefer. I'm very happy with my final decision.
