The result should be better motion performance, although as usual the benefits are pretty subtle. > The new 75-inch 6 series' chief competitor is the Vizio P-Series, our previous pick at that size for best picture for the money -- and it also costs about $1,800. Based on my comparison between each series 65-inch sets, I slightly prefer the image quality of the TCL, but both are excellent. And of course the TCL's built-in Roku smart TV system is much better than Vizio's SmartCast setup.
