Our Verdict
LG GX OLED
Sony X80J
The LG GX OLED is better than the Sony X80J, but they're also very different TVs. The LG is a high-end OLED that can produce perfect blacks and has a near-instantaneous response time. The Sony, on the other hand, is an entry-level IPS TV, so it has a low contrast ratio and lacks a lot of the features that the LG has. While it has good viewing angles, they're not as wide as the LG's viewing angles. The LG outperforms the Sony in almost every way.
