No. I don't have them side by side. I have however seen both in action and when you see a TV that reproduce such startling standard definition TV picture picture quality, and then some you know you've got something very special on your hands. The 42PX700 is s good TV but the 42PX600 if indeed you can even get one now, runs rings around both the 42PX700 and 42PX600. The sound too on the 42PX600 is fantastic!!!
May be there are others on here that might happen to testify to the above?
