Plasma every time.
They use less electic than lcd, on standby it's almost nothing unlike crt.
They don't get hot, you put your hand over the top of an lcd :S
Plasma has better contrast etc etc & put a black image on both & plasma is unbeatable.
They last 20 yrs or more so you'll be sick of the sight of it before it goes pop.
For fast moving images ie sports, again plasma, if you watch sky footie you'll be amazed.
They don't attract dust so dont need cleaning.
