The LG 55" OLED TV generally provides superior picture quality, particularly in dark rooms, with its perfect black levels and excellent contrast. It also supports Dolby Vision and offers very low input lag for gaming. The Samsung 55" QLED TV, however, can be brighter and more suitable for well-lit rooms, and some models include anti-glare coatings. The best choice depends on the viewing environment and specific feature preferences.
