Yeah, I'm leaning towards the LG one because I saw some reviews that say the Sony 40w600 is slow.
Screen takes 20-30 sec to change video inputs and takes 10 seconds to change channels but after a while speeds up. But after turning the tv OFF for 1hr then turning it ON the slow cycle repeats again. They say the picture quality is great though.
While the LG one has a fast smart tv interface the webOS, 120hz and 42 inches. The say the picture quality is only good.
Will have to see it in shops then to make my decision.
