Sony X90J vs Sony X95K

The Sony X95K is a higher-end and newer model than the Sony X90J, so it's a bit better overall, but it's not a significant improvement. If you care about peak brightness, the X95K is the better choice as it gets brighter and has much better reflection handling if you want to use it in a well-lit room. However, if you watch content in a dark room, the X90J has a better native contrast ratio, so it displays deeper blacks.
