I currently have a Panasonic 58" VT25 in my living room. There is nothing wrong with this TV, but eventually I plan to move it into our bedroom. I really like picture on my TV and compare it often with my father-in-law's Samsung LED (3yr old 7k series). His LED does seem to have a sharper picture, but has a lot of issues with motion (could be the cable provider) and the whites are too bright.
I don't "need" to replace my TV now, but with the Panasonic...
