Our Verdict
Samsung Q70A
Sony X85K
The Samsung Q70A and the Sony X85K are both good TVs with similar features. There isn't much difference between them, so choosing one over the other comes down to personal preference. The Q70A gets a bit brighter and has better contrast, so the overall picture quality is slightly brighter, but it isn't a significant difference. If you watch content in Dolby Vision, the Sony TV supports it, which the Samsung model doesn't.
