If you prioritize overall picture quality, especially in dark environments, and can afford a premium price, the LG C3 (OLED) would be a better choice. It also has a slight edge in gaming performance. However, the LG C3 may not be as bright as an LCD in well-lit rooms. On the other hand, if you're looking for a more budget-friendly option that still offers good performance, the Sony X90K (LCD) is significantly less expensive and offers decent performance across viewing content. While its picture quality isn't as high as the LG C3, especially in dark scenes due to its lower contrast and black uniformity, it's a capable TV for various types of content including sports and movies. Furthermore, the Sony X90K has great speakers built-in, which could save you from needing to invest in a separate sound system. Give Feedback

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."
