Are you trying to find a TV with 100% good reviews?
There have been TV's rated as "Best" by some sites, and the same TV mediocre by other sites. Take away the flashlighting issue and the 7600 has some of the best reviews by users. Also, Dell does not have the 7600 series on it's site, so they won't be recommending it, not to mention Dell seems to have a large share of both Proven (Court action) bait and switch and many customer complaints that may not have had an actual court action. Trusting them for any advice on TV brands is not what I would even consider. They will promote whatever they have the most of and or make the most on.
There are gamers here posting, I would take stock in their reviews. (And you are)
All you can do is what you are doing, read reviews both professional and in forums like this, balance them out and make a choice. I was set on a Samsung till I actually saw it in the store. The LG was an obvious better looking picture even after playing with both of them. (Except for blacks)Edited by tampa8 - 12/7/12 at 1:26pm
