If you're looking for superior picture quality with deeper blacks and vibrant colors, the LG B3 OLED is the way to go, but it will cost you more. This TV excels in dark room viewing and has a wide viewing angle, making it great for movies and general content watching. However, OLED TVs are more prone to permanent burn-in, so if you watch channels with static logos or play the same video game with constant on-screen elements, this could be a concern over time. On the other hand, the Sony X90K LCD offers a solid picture quality at a more affordable price, and because it's an LCD, it doesn't have the same burn-in risk. It's also preferable if you often watch TV in bright rooms since it can get brighter than the LG B3 OLED. This TV provides a good experience for sports and gaming too, but the picture quality when viewing from wide angles isn't as good as what you get with the LG OLED. If budget is a top concern and you need a TV that performs well in various lighting conditions, the Sony might suit your needs better. Give Feedback

The LG B3 (OLED) is excellent for movies & TV, while the Sony X90K (LCD) is good.
The LG B3 OLED provides exceptional contrast and perfect black uniformity, enhancing movie and cinematic TV viewing, especially in dark scenes, and it has wide viewing angles allowing for consistent picture quality when seen from different positions. The Sony X90K LCD, although it offers good contrast and local dimming, can't match the LG's performance in these areas, and its narrower viewing angles can lead to color and contrast shifts when viewed from an angle.

Al Griffin | December 2022
"As Sony’s next-to-flagship LCD TV, the X90K series delivers impressive performance for the price. The XR90K had fairly accurate out-of-box color. The TV’s multi-position stand lets you either set the screen flush with any stand its mounted on or elevate it to clear space for a soundbar. With the latter option, you get around 3 inches of clearance enough to accommodate most soundbars. The X90K’s excellent suite of gaming features ranks it up there with the best 120 Hz 4K TVs."
