Plasma or LCD?

i heard plasmas have more deeper black colors but dont last as long. and if you have your kids leaving fingerprints on the screen and dont clean it up right away, the prints burn onto the screen forever. i have a VIZIO LCD 1080p which is the best bang for your buck, has the best overall pictrure quality with HD recievers. VIZIO resulotion i think looks even better than a couple of my buddies' SAMSUNG LCD tvs, they looked a little grainy.
