If you prioritize incredible contrast and picture quality and don't mind spending more, the Sony A90K OLED is an excellent choice, particularly for movies and gaming in darker rooms. However, its performance in bright rooms is less impressive. On the other hand, the Sony X90J LCD is more budget-friendly and still offers very good performance for a range of content, including sports and gaming with good picture quality, though it can't match the A90K's excellence in darker scenes. The X90J's viewing angles and reflection handling aren't as strong as the A90K's, which could be a drawback in well-lit rooms or for wide seating arrangements. Both TVs support the latest gaming features but the A90K might provide a slightly better experience due to its superior response time and black uniformity. If you're looking for better sound quality and can invest in external speakers, either TV will do, but if you're relying on built-in speakers, consider the A90K's slightly more powerful setup.
