Firstly, that Panasonic tv pwns all. It is probably one of the best decisions you could make when purchasing a flat panel tv. It is the highest rating of any tv on CNET.com or Consumer Reports. As a gaming tv it would perform very well, and don't worry about burn-in on it becuase this tv has built in features that make burn-in virtually impossible(like pixel orbiters).

The best Samsung at this size is the newly released 950 series that is available in a 46" and 55" cut. This tv has it all, LED backlighting, 120hz motion, and a stylish cabinet.

LCDs can experience motion blur with fast moving images(games), but they don't really have glare issues and use less electricity. Plasmas rarely experience motion blur, but tend to experience glare in rooms with a lot of lights or windows.
