If you are looking for a more budget-friendly option, the Sony X85K is often significantly less expensive and offers good overall picture quality, excelling in gaming and sports content. On the other hand, the Sony X90J, while typically more expensive, provides a higher overall picture quality, particularly shining in dark room settings. It also has good bright room performance, making it a versatile option if you are willing to invest more. Both models may not be ideal if used in very bright rooms as their performance under such conditions is not the best. Consider how you prioritize gaming, dark room viewing, and budget when making your decision. Give Feedback
