No One can beat Sony in terms of Picture Quality but only disadvantage of Sony LEDs are they don't support all kind of Video format (specially mkv) through their USB Port.Also you have to be cautious for After Sales Service as their after sales service is completely chargeable.Lastly you will be able to connect only FAT and exFAT file system Storage Devices through USB.
Do not get Sony. Their edge lit panels are pathetic. Light bleeding from edges is big problem if viewing dark scenes in dark room. The TV remote interface software of Sony is clumsy at best. Can't wait for Apple to release their own TV sets and light the asses of these manufacturers on fire just like they did with phone and tablet. Some companies need wake up call before they start making worthwhile products. Since I purchased a Samsung TV today, I would say that 46 inches 3D TV from Sammy looked stunning with better UI. It was coming for 110000.
