I wanted to order my new MBP on the first Tuesday they came available - but waited almost two weeks because of this issue - and it literally drove me mad. I spent hours in Apple stores staring at screens. I read every forum entry possible. I examined the lighting in every place I would possibly be using my machine.
Heck, I didn't invest this much soul searching when I got married !!!
Ultimately, I decided what people here have already said - BOTH screens are really excellent but there are characteristics of each which will resonate differently with people. Thus, there is no right answer - but only a right answer FOR YOU.
Finding out what that is is rough if you can't examine the goods live - but there are some decent photos on some of the threads. Just watch out for the ones that try to generate maximum glare on screens by photographing them at angles you would never consider in daily use. Yes, you can make something out on one screen in a maxiumum glare scenario - but how do you feel about them when you are using them normally?
For me the final test was asking myself honestly which screen I wanted to look at all day. I could accept both and be happy with both - but after too much time staring at them both I really felt that one of the two choices was what I wanted in front of me all day. I would just be much happier looking at that screen - so I bought it.
Now, I am not going to tell you what my choice was.... because you need to make your own mind up and anything I could say would have been said 50 times here by other people already. It doesn't add anything. My message is that this is a rough but a personal decision - so get through it the best you can and be happy with the result !!
If you guess wrong... well, some people here have exchanged their machines after the fact. Annoying but it can be done....
