.. Lcd is brighter, usually higher resolution(1080p), IMHO better contrast, runs cooler, uses less power, is less prone to burn in(yes its still possible, just less likely), and weighs less (slightly) .. also has less glare
stick with vizio(great low end), sharp, samsung, or sony
.. Plasma is cheaper, bigger for the money, has better viewing angles, usually not as high of resolution(most people don’t need 1080p), not as bright, less contrast, some say more accurate(possibly less vivid) colors. Looks great in a darker room, but may be weak for brighter room. Plasma may develop burn in monitor displays same graphic for extended time(most tv watching won’t be a problem). Usually the glass screen is more prone to glare.
stick with Panasonic, Pioneer.
Both will look great with todays HD signals. Good luck.
