From my personal experience, just for general reference, not fact though...

LCD/LED
TVs are much brighter.
Colours are saturated and catchy, good for drawing attention.
Very crisp clear and sharp
Higher end has better motion flow control
Slim and sexy design
Good for PC and games than cinematic movies

Plasma
Natural colours, may look dull beside LCD
Smooth motion, good dark scene
Render SD better, especially on Astro
Suit dark room viewing
Gentle on eyes for long viewing
Good for movie and sports

My two cents....

Where to get 5 year warranty nowadays? Your plasma is like few years back where Panasonic still honored 5 year warranty. Now, all cut cost, warranty period also cut....haiz
