Samsung 40' Lcd 1080p vs Toshiba 42' Lcd 1080p

I have looked at both sets quite intensively over the last couple of days. The dealers are telling me the Toshiba cinema pro series Lcd 1080p is superior to the Samsung mentioned above. Do any of you have experience with these units? I have also heard that the sound quailty of the Samsung is less than desirable. Any experience there?
