Depends on how big of a pic you want and what you watch. They are both good units but the bigger picture on the sony is quite attractive. If you watch alot of sports of fast action stuff the Sony will do better, it also will have better black level.
I am trying to decide between the Sharp Aquos 32" LCD and the Sony Grand Wega 42" LCD Rear Projection TVs. Any thoughts? Thanks
