The Sony X90J and the LG C1 OLED are very different TVs. The Sony is an LED TV with a VA panel, while the LG is an OLED. The LG has a near-infinite contrast ratio and can produce much deeper blacks than the Sony. It has a wider color gamut, much quicker response times, and VRR support. Since the LG doesn't have a backlight, it doesn't have any blooming around objects in dark scenes like the Sony. It handles reflections better than the Sony, but it doesn't get as bright, so if you tend to watch TV in a well-lit room, the Sony might be a better choice. The LG has a much lower input lag, and unlike the Sony, it supports HDMI 2.1 on all of its ports.
