Plasma or lcd?
You'll probably get a lot of opinions on that question
The majority of people would say pioneer has the best plasma screen.
With lcds I think opinions will be more varied. Manufacturers buy their panels from other manufacturers and that confuses the issue even more. Toshiba, sony, sharp, samsung, lg, mitsubishi, jvc etc... all have excellent tvs. The screen I hear a lot about is the panasonic but the largest size is 37".
