The ONLY reason to get an LCD is if you have a super-bright room that you can't control the light in.
Otherwise, Plasma is superior in every way, OTHER than potential brightness and power consumption. (and if the minute difference in power usage is a deal-breaker for you, then you probably shouldn't be buying a TV of any kind to begin with)
That's why LCD's seem to look better in stores. Stores are brightly-lit, and LCD's are set on "vivid" out of the box, which will make the picture seem better IN THE STORE. But nobody has THAT much light where they watch TV. Go to a Best Buy that is a Magnolia store (like Crabtree Mall) and they have a dark area where they have the higher-end TV's of all types. You can get a better idea of what you like there.
In every other facet, Plasma is better. Only a very few, absolutely top-of-the-line LED/LCD's, such as the Sharp Elite and the Sony XBR's, can even think about pulling even with a Plasma. And they cost a LOT more than the top shelf Panasonic Plasma. Like over double. And if you watch sports or game, and don't like the picture to get a little blurry in fast moving scenes, you want Plasma. It's still unmatched, except by DLP. DLP is still the daddy for sports and gaming, but they're going away.
BTW, you can still get the Mitsubishi Laser Vue DLP's, and they are damn close to a Plasma. 75", I think they are. As long as you don't want to hang it on the wall.
