Hi - I have Sony 40" Google TV with me and I am getting a Frys replacement for it as there was a defect in the piece. Frys is ready to give me 47GA6400 as a replacement or I can shell a few 100$ and get the 55GA7900 - I want to check if any of the TVs are worth buying? I loved the Sony TV features but wasnt impressed with the picture quality. If I am comapring the LG line up with Samsung Smart TVs - what would people recommend?

Thanks a lot!

Thanks,
Arpan
