You can find out in this comparison guide.

Quick Summary

When compared to the X85J and X90J, the X80J has the lowest input lag. However, it also has the worst contrast ratio and dimmest HDR brightness levels. Furthermore, the X80J model does not support 120 frames per second, HDMI 2.1, local dimming or Variable Refresh Rate.

The X85J has the best contrast ratio when compared to the X80J and X90J. While it has no local dimming, it does feature a wide color gamut and outperforms the X90J in select scenes when it comes to HDR brightness. This TV also supports 120 frames per second and HDMI 2.1 while Variable Refresh Rate is expected to be added via a future firmware update.

When compared to the X80J and X85J, the X90J has the highest overall HDR brightness levels and is the only television to support local dimming. However, it does not feature a wide color gamut when compared to the other two 2021 Sony TVs. The X90J does support 120 frames per second and HDMI 2.1 with Variable Refresh Rate expected to be added in a future firmware update.

Overall, we recommend getting either the X85J or X90J if you want to futureproof your television of new and upcoming gaming systems as both of these support 120 frames per second, HDMI 2.1 and Variable Refresh Rate.

The X85J has better contrast, colors and input lag reduction than the X90J. However, the X90J should provide a better HDR experience.
