Let me tell you something about these forums... It appears as though the more you read, the more knowledge you will gain: Both good and bad!
Like an earlier poster said, most of the TV forums will start out very positive, then take a turn for the worst. And while the posts start to turn, the average buyer is reading the post thinking they are getting ready to make the best purchase on a set, only to find out by "reading all of these forums" that their new set is full of problems. Most of which, the new buyer does not have a clue about until he reads about it on "these" forums!
I think that you should make your decision based on your budget and your TV desires and then do your best to enjoy your set. Then visit the forum every blue moon to get advice on tweaking you new visual wonder. If you come here looking for a problem, then you WILL find a problem.
It's sort of like what audiophiles go through. They are so busy evaluating their equipment that they can't enjoy the music!
My 60A2020 will never be the perfect set. Why? Because I like to read these damn forums too much!
But these forums have not stopped me from enjoying my set. If I look really hard, I am sure that I could see purple blacks, SSE, or the green blob on any set. Especially if I click my heels three times and chant! But right now, my set doesn't have a problem, and I ain't looking for one either.
My advice would be to buy the set, then tweak it to YOUR satisfaction, and then enjoy! Good luck!
