Good comparison, I am much with you.

One more thing about TVs - do not forget where and when you watch it mostly. Plasma is not that bright so it's not the best choice for daytime living room viewing. LCD which is brighter will do a better job.

I believe most LEDTVs now are still LCD panels with LED backlit to give true black background. I do think it is superior, cost more of course. Like it or not, seems the industry is going that way. Most shops now have LEDTVs from Sony, Sharp, Samsung, LG. Panasonic seems to be the only brand w/o it.
