Plasma is much better for movie, because of deep dark background. image quality is more nature. LED is more shape and bright, maybe better for TV experience when you light up the lamp at home.
V10 and V20 's panel is differnt, I did A/B test, personally I like V20 panel more. so I picked up V20.
If you pay it in Cash, it should be 2K cheaper at MK shops.
