Our Verdict

Sony X85K

Samsung Q70C [Q70, Q70CD] QLED

The Sony X85K is better than the Samsung Q70C. The Sony is better than the Samsung TV in every category, except in its low-quality content smoothing capabilities, which are sub-par on the X85K. The Samsung is also better than the Sony if you want to use your TV as a PC monitor, as the Sony can't output chroma 4:4:4 properly with 4k @ 120Hz signals, although 4:4:4 works well with 4k @ 60Hz signals. The Sony also doesn't support 1440p. Otherwise, it's better than the Samsung model in every other category and supports Dolby Vision HDR and ATSC 3.0, so it can stream over-the-air 4k channels.
