R8 series Roku TV: On paper this set looks like a serious rival to TCL's 6 series, CNET's favorite TV for the money, which combines Roku's superb smart TV system with the picture quality chops of full-array local dimming. The R8 has a healthy 64 zones of dimming on the 65-inch size, wide color gamut, 700 nits of brightness and Dolby Vision, all for less than the TCL 6 series. Shipping "later in 2019" the 55-inch size costs $600 and the 65 an aggressive $750. 

H8F series Android TV: This set offers all of the picture quality features of the R8 but with Google Android TV smart system instead of Roku's. Google Assistant voice control is built-in and the set also works with Amazon Alexa. It will launch in May 2019 starting at $400 for the 50-inch and up to $750 for the 65-inch.
