I like plasma if the location where the tv will be is not subject to glare.
I like LCD for rooms that have a lot of glare. As such, I'm spoiled and have both :)…

Both tube tv's died a two years ago, so an upgrade was needed. I'm sort of crying now, because plasmas and lcd's are soo much cheaper these days.

If you plan on using your tv as a monitor for a computer, I'd say LCD is better. There was some initial concerns about image burn-in for plasmas. personally, I don't think it's really an issue these days.

Whatever you buy, just don't be one of those annoying people that invite your friends over and make them go through millions of pictures on the new display 🙂
