I don't know. Looking at a wall of HD TVs at Best Buy or Future Shop, I don't see a whole lot of difference in display types nor brands, except perhaps how they are set up. Showing HD material, to me they are all 'similarly good'.

I'm still using a 50" Sony XBR rear projection LCD from 2003 - now on its second bulb. That technology did not give the best blacks but normal daylight type scenes are stunning to my eye & still very satisfying. At the exorbitant price that I paid, I'm going to run it till it blows up & then it will probably be an LED/LCD.
