Well I can't really help you in the USA, but in the UK/Europe CRT's disappeared years ago, there are hardly any Plasma's (only Panasonic, LG, and Samsung still make small numbers of them - and that number is likely to drop), and almost all (if not all?) LCD sets have LED back-lighting.
Best makes are Sony and Panasonic, mid-range makes are Samsung and LG - pretty well everything else is cheap and poorer quality.
As I understand the American market, it's been mostly cheaply made badged sets for even longer than the UK?.
