well, I suggest you take a look at this list: http://www.chip.de/bestenlisten/Bestenliste-Fernseher-ab-43-Zoll--index/index/id/1024/
"LED TVs" today are just using LED backlight, the picture itself is still made from LCD, so LED-LCD would be a more accurate term for these TVs. Sony showed "Crystal LED" last year, which is a TV made from anorganic LEDs alone, but it's doubtful that will make it to the market any time soon.The other pure LED Tvs ofcourse would be O(rganic)LEDs.
Plasma still delievers superb picture quality (well, only Panasonic really still are in the market - the other plasmas you can buy todays are very old models you should stay away from) and usually are cheaper at the same size/same features , but consume about 2-2.5 times the energy.
