If budget is a major concern, the LG B3 provides a cost-effective choice and still offers an excellent viewing experience for movies and general TV watching. However, the Sony A90J, while more expensive, provides better overall picture quality, particularly for upscale content and when watching in brighter rooms due to its higher brightness capacity. The Sony A90J also has a more versatile sound system with a more comprehensive range of audio formats. If gaming is a priority, either TV will perform well as both offer features like 120Hz refresh rate and support for 4K gaming at high frame rates. Give Feedback
