Look at the multiple discussions over at avsforum.com. They have beaten this discussion til the horse stopped breathing. As for your question, There is no such thing as a LED HD in a size that would be able to have in a consumer home. LCD sets come in various flavors (LED, CFL), as for worst to best, it would be in the following order: DLP at the bottom, LCD with CFL backlight next, LCD with LED, then Plasma. 3D sets are now down in price, that anyone can afford them, even though most that are buying are not doing it for the 3D.
We have a Sony 32" LCD in our Bedroom, and in our Living Room, we have a Panasonic 42" Plasma. Both are good sets, and have their pluses and minuses. The minus on the plasma, is now we are wanting a little larger, due to we watch a lot of movies on it, and Football season is here, so we want to move up in size. The Sony, we watch regular tv, and have a Roku for Netflix.
I would though, stay away from any set that has built in apps, because people are seeing still a lot of problems with the quality when watching Netflix, and the apps cooperating, very poor.
