Our Verdict
Sony X90K/X90CK
Sony X80K/X80CK
The Sony X90K/X90CK is a higher-end TV than the Sony X80K/X80CK with better performance. The X90K gets brighter and has deeper blacks, meaning the overall picture quality is better, and it's better for both dark and bright rooms. Also, if you're a gamer, the X90K is a superior choice as it has a higher refresh rate and more features. However, if you have a wide seating area, the X80K has a wider viewing angle that makes the image remain consistent from the sides.
