I am selling my PN59D6500 to a friend and am going to make a small upgrade to my TV. Right now I am looking at either the TC-P60ST60 and the PN60E8000 televisions but am completely open to other opinions. I have had a few Panasonic plasmas and I like them however I have heard great things about the Panasonic panels. It seems this year that there is a big gap in the Samsung lineup from the F5500 to the F8500 which is too bad.
I use my tv for gaming, movies, and tv shows. So input lag is a factor however for games that I am really worried about input lag I use a gaming monitor. I really like deep black levels which is what got me looking at the Panasonic in the first place. I do watch 3D movies from time to time but I care much more about 2D quality than 3D quality.
