Yeah, plasma may top the PQ meter, but there's other factors that might play into a purchase. For me LED's energy efficiency, low heat output, and fast response time are all pluses. And plasma's are all 42"+. Too big for my setup. And the Panasonic black level degradation of last year's plasma's is rather disconcerting.
Sorry man, with all due respect, I think there are some important misunderstandings going on.
I've never owned an LCD or plasma. Or any flat panel for that matter.
Black level degradation, whether it's the floating blacks or the rising blacks, is essentially a non-issue for almost everybody. Do you watch in a cave, have the panel calibrated whether professionally or with the right equipment? Even a plasma with a rising black issue will still blow away the blacks of most LCDs.
Energy is another issue. Yes, LCDs use less energy. But, it's closer than you think. LCDs always have the backlight on, and therefore are always using the "max" power consumption. A plasma will only use the max consumption when the screen is brightest 100 IRE white.
Once the displays are actually calibrated, and not blue shifted dynamic blinding, the plasma's energy consumption drops further. Again with LCD, it remains the same.
As for response times, don't even go there!! Plasma cells only suffer the latency of an electrical current exciting the gas inside them.
