My business is selling and installing audio video and home theater systems. The best TV on the market is a Panasonic Plasma.. period.
The added benefit is that Plasma TVs are cheaper.. Best Buy will try to sell you the Samsung because they still make $100-600 (depending on the size) off of it while they make about $15 off of the plasma. My supply chain is through distribution so I make $0 selling a plasma if I try to price match BestBuy but I still recommend them to all of my clients.
