A thread like this pops up every other week on this forum...
The OP has already made the generalization that plasmas have better picture quality in the title.
As a consumer you really must compare Model VS Model, not display technology VS display technology.
What really constitutes "better" picture quality though?
TV sets today are over-driven right out of the box.... and most all of them look terrible.
There are LED-LCDs that have better color accuracy, grayscale linearity and the correct white point just by switching a picture mode, and then there are plasmas that get all that wrong, with an unadjustable color gamut, colored grayscale, and uniformity issues.
You can reverse all of that and say the same thing backwards: there are plasmas that get all that right, and LCDs that butcher color, etc...
I have seen some terrible plasmas, and some terrible LCDs...
The fact of the matter is both technologies have good eggs, and bad eggs.
I have had countless Panasonic Plasma sets (in the past), and I have a few LCDs and an LED driven LCD set today. I think they both have ups and downs. I could not stand spacial dithering honestly, and needed more light output in the viewing area, so I made the switch.
I went from a Panasonic TCP50S1 to a Samsung UN55D6000, and if anyone knows the history and performance of each set, then they will also know that the Panasonic was a terrible performer in comparison to the D6000 (a set that got color and grayscale correct out of the box).
So it all really depends!My advice: A consumer should buy the set that performs the best regardless of the technology that drives it. I personally like Home Theater's reviews as a reference. Once you find the best performer for the price, then you know whether you are buying an LED driven LCD or a Plasma.
Don't be eager to generalize that plasmas always outperform LCD sets however, as many plasmas have got it wrong. There are plasmas out there that cannot achieve linear grayscale's, have bad color gamuts that cannot be adjusted, and simply cannot produce any light output before going wonky.You will find inexperienced complainers on this forum also. You have LED-LCD guys crying over flashlighting and uniformity, but they are running their set at 80ft/l, and cannot figure out why they are experiencing light bleed. Then you will have people crying on the plasma end that they cannot get a linear grayscale on their plasma set, but have the contrast overdriven when they attempt calibration, etc, etc, etc. The complaints go on and on.
I still recommend plasmas in most lower light situations, but there are pieces of sh*t out there, from the flagship brands. You really must compare model to model, not display technology to display technology.
