Our Verdict
LG C1 OLED
Sony X91J
The LG C1 OLED and the Sony X91J are different types of TVs. The LG has an OLED panel with a near-infinite contrast ratio for deep blacks and wide viewing angles, and the Sony has an LED panel that gets brighter and doesn't suffer from the risk of permanent burn-in. The Sony is available in an 85 inch size only, while the LG is available in a variety of sizes, including an 83 inch model. The LG is better for gaming because it has better motion handling. The LG also has lower input lag for a more responsive gaming experience, and it also has much better reflection handling.
