Question: compare Sony 40ex620 vs. Sony NSX-40GT1

I was ready to buy Sony's 40ex620 TV (because of measurements) when someone suggested the NSX-40GT1. I know that the ex620 is a new 2011 model but I don't see anything in the way of reviews by users or people in the know (total of 3 on the whole internet). Is one better than the other? I'm not a gamer! Thanks
