Plasma TVs have had trouble over the years. LCDs have dont a very good job on keeping their quality over the years. (look at a old LCD monitor)
The only reason I say what I say about the Samsung/Sony TVs. Is because they look the best, and they are the best.
I think the color accuracy, the contrast (the visible, not numbers)... and other stuff that I feel makes a TV look better. The Samsung/Sony 40inch screens are bright too.
The reason I say Samsung/Sony, is they both have the same screen I think, and the sony has a slightly superior video chip. (put them side by side, and you will see what I mean)
