I just went through this a couple years ago so my info is definitely dated but here's what I came up with for the big players... being samsung, panasonic, and LG. The sammys were on top for everything but they were known for having a little buzz. I bought a sammy and yes it does buzz a little. when a movie is on or whatever no way you'll ever hear it. The panasonics were said to lose their nice black blacks over time but great picture otherwise. The LG's weren't really in the same league picture wise (if you really wanted to split hairs) but you got a great picture and a big TV for a great price. Personally I don't think you could go wrong with any of those brands but read reviews for any model you're considering. The only thing I would suggest is making sure where ever you buy it they have atleast an exchange policy. In the stores they have messed up settings, showing pictures that will show them off so you'll look at one and think how vivid the colors are and buy it. It will probably look a lot different when you get it home and put the game on.
Just my 2cents.
