Our Verdict
Sony X85J
Sony X91J
The Sony X91J is better overall than the Sony X85J because it's a higher-end model. While we tested the 55 inch model of the X85J, it's also available in an 85 inch model like the X91J. The X91J has a few extra features that make it better overall, like a local dimming feature. Motion also looks smoother on the X91J due to its quicker response time. On the other hand, the X85J has a higher native contrast ratio, but this may also vary between units.
