I choose LCD, (42" Samsung if anyone cares). LCD is better for viewing in a dimly lit environment Plasma works best in bright light where LCD is hard to watch. LCD uses less power, the screens are a little tougher. Plasma is brighter and sharper and you can buy larger plasmas than LCD. Unless you're buying cheap, the picture quality is the same, modern LCDs have no problems with latency or response time both are good for HD, SD always depends more on the kit used for upscaling. Plasmas get screen burn - this put me off buying a plasma, so I saved some money and bought LCD. Usually, you see the screen burn where the station logos sit, so it isn't that big a deal until you watch a DVD or play a game. Most manufacturers make both LCD and Plasma, this should tell you there's not that much to choose between them.
