If you value a superior overall viewing experience and don't mind spending more, the Sony A90J is a better choice. It delivers slightly better picture quality, especially in handling reflections and color accuracy, which is beneficial for diverse content and well-lit rooms. On the other hand, the LG B1 is less expensive and still provides excellent gaming performance and picture quality, though it may not handle bright room conditions as well as the Sony A90J. Both TVs offer OLED technology, ensuring high contrast and deep blacks suitable for movies and dark room viewing. However, neither is particularly bright, which is a consideration for daytime viewing in bright rooms. If budget is a concern, the LG B1 offers a high-quality viewing experience at a lower cost. If you're looking for premium performance and can invest more, the Sony A90J may be the better option. Give Feedback

The Sony A90J (OLED) is excellent for sports, while the LG B1 (OLED) is very good.
The Sony A90J excels in sports viewing because of its superior motion processing capabilities, ensuring smoother playback during fast-paced games, and its reflections handling is on par with the LG B1 which also mitigates glare effectively. While the LG B1 offers excellent response time and wide viewing angles, suitable for games with fast movements and larger groups watching together, its motion processing is not as advanced as the Sony A90J's, making the latter a better option for highly demanding sports enthusiasts.

The Sony A90J (OLED) and LG B1 (OLED) are both very good for news, talk, & other TV.
The LG B1 and Sony A90J both deliver deep blacks and prevent blooming around bright objects due to their OLED panels with perfect contrast and pixel-level dimming. However, for watching news and talk shows, the Sony A90J has a slight edge with better upscaling of lower-resolution content and more accurate colors straight out of the box, while both have comparable SDR brightness making them good for viewing in most room settings.

The Sony A90J (OLED) and LG B1 (OLED) are both good for bright room.
The LG B1 is well-suited for bright rooms due to its sufficiently high SDR brightness and excellent ability to reduce reflections; however, its HDR brightness is only fair, which might make HDR content less impactful in well-lit environments. In comparison, the Sony A90J also offers good SDR brightness and excellent reflection handling, while providing better HDR brightness, thus making bright HDR scenes pop more even in sunlit rooms.
