Our Verdict
Samsung AU8000
Sony X80K/X80CK
The Samsung AU8000 and the Sony X80K are similar TVs, but the Sony is a bit better. The Sony has a better viewing angle, making it the better choice for watching shows or sports in a group setting, as the image doesn't degrade nearly as fast from the sides. The Sony is also a bit better for playing video games, as it has a slightly faster response time and supports 1440p. Regarding HDR, the Sony is also a bit better because of its higher HDR peak brightness, wider color gamut, and better color volume, so it has more vibrant and lifelike colors, and highlights pop a bit more than on the AU8000.
