Suggestion:
No matter what anyone says, a good, brand name 1080p plasma is better than any LCD around.
It has better viewing angle (LCD washes out if you look off axis). http://www.consumerreports.org/cro/electronics-computers/tvs-services/tvs/tv-buying-advice/types-of-tvs/tv-display-technologies/lcd-or-plasma/lcd-or-plasma.htm
It has better black level (only the newest LCD that has LED backlighting with local dimming comes close.) http://www.consumerreports.org/cro/electronics-computers/tvs-services/hdtv/lcd-tvs/led-backlight/overview/led-backlight-ov.htm
It does not suffer from motion blur like LCD's do. (and the latest LCD 120 and 240hz models actually cause viewing problems!) http://www.lcdtvbuyingguide.com/lcdtv/120hz-240hz-60hz.html
However it is just like VHS and Betamax. Betamax was better technology but VHS won out in popularity.
