I still maintain that it doesn't matter what any expert (proper or armchair) tells you about TVs and which one is 'best', it's all down to the individual and their eyeballs.
I directly compared (as in was in a shop and had the three TVs side-by-side, all running the same BD and 360 game) an LCD, and LED and a plasma TV. I ended up with the Samsung 7-series 55" LED, simply because it looked far superior to my eyes. I've no doubt if you ran off and did all kinds of scientific tests that the plasma would have better blacks and the LCD wasn't far behind the LED, but for what I wanted it for it fitted me perfectly.
Whilst it's true that you could buy almost any telly and be happy with it as it'll never be seen next to another one when it's in your home, you really do need to get out there to any of the big chain shops (Comet, Currys ets) and physically see the difference in picture for yourself. Bring in one of your own BDs that you know really well and that will test the screen (so anything fast moving and dark is good, I used Independence Day) and make them put it on the screens for you. Do it at a quiet time and they will help you out as they want the sale, although you still don't have to buy from them in the end. Don't just buy a TV over the internet because all the reviews say it's good: It may well be, but it may not suit your eyes.
