Plasma screens don't do shades. The cell is either lit or unlit. That means for shades of colour they just flicker very quickly. If you're looking for it, you'll see it; otherwise you'll never notice. However, some screens (like my Panasonic) use a pseudo-random speckle, reminiscent of Floyd-Steinberg error diffusion, whereas others (like a Fujitsu screen I tested)use a fixed dithering pattern, reminiscent of Windows 3. Try the screen with something dark, like The Crow, or Alien or some such.
My gripe about LCD's is that near-blacks are often darker than pure-blacks. Especially if you're not looking dead-on at the screen. That really riles me, which is why I went for plasma. Again, check it with something dark. I recall one of the old Philips plasma screens being similar in this department.
LCD's tend to have a higher resolution, so if you want good HDTV they may be the way to go. My plasma is only about 820x480 res (good for 480i and 480p images, although it'll decode and interpolate up to 1080i). Plasma screen are (in my experience) much heavier, so if the screen is to be wall mounted on a dry wall, they may not be appropriate. They really need bolted into brick or breezeblocks.
Now, your next problem is speakers (if they're not built into the screen). If you have a nice flat screen on the wall, you don't want your speakers taking up the whole room... I'll leave that little problem with you :)
