Meaning of 50inch plus = Plasma. Is that anything over 50inch in size is generally speaking plasma's playground. Image quality far far superior to an equivalent LCD(LED) screen.
Agreed.
Buy using the one that gives the best picture...and to my eyes, at 50" (even 42") and above, PDPs give more natural colours, blacker blacks and handle motion better.
Basic rules are viewing distance will dictate viable size, and if you have a light room get a LCD, if a dark room Plasma is better.
In reality, if using only HD sources, you can double the set size suggested by most traditional thinking.
I agree on the light/dark room comments though.
LCDs go brighter - and often less natural.
PDPs go darker without losing detail.
If you are looking in a shop like Currys, see if you can get the remote and change the picture mode to 'Cinema' if it had one. That's likely to have the closest to natural colour reproduction.
Buy what looks best to your eyes.
