I just bought a 2014 E series 60" a month and a half ago, so glad to hear this is basically the same panel with a worse stand. I was worried the new panel would be better and I would have buyer's remorse.
It's a good set. I think the normal color temperature is a little too warm, perhaps under 6500k, but I don't have professional equipment to test that with. The middle color temp, labeled "computer," is a little too cool, so it's frustrating. Either way everything else about the set is pretty great. Blacks are rich, motion is pretty solid for LCD, everything pops how you want it too if you calibrate it that way. I had a plasma before (a Toshiba) and this set looks almost as good, very close, without the worries of burn-in and for a lower price. I am satisfied.
Will be interesting to see new people posting calibration thoughts in here. I still mess with mine here and there, struggling to find the perfect settings.
