If prioritizing overall picture quality and excellent gaming performance is key, the LG C3 is an impressive choice, with its excellent scores across the board, including for sports and movies, and it's less expensive than the Sony A90K. The LG C3 stands out with better brightness in both SDR and HDR, which translates to a better viewing experience in bright rooms. It also has superior input lag performance, making it highly suitable for gaming. The Sony A90K offers very good performance too, especially in a dark room where OLEDs excel, but it comes at a higher cost and has fair bright room performance which could be a downside if you watch TV in a sunny room. Both support similar HDR formats and have OLED screens with wide viewing angles, but the LG C3 offers Dolby Atmos support directly. If budget is a concern, the LG C3 provides a well-rounded experience at a midrange price, while the Sony A90K might be for those who are fans of the Sony ecosystem and are okay with a higher price for its features.
