The Samsung QN90C (LCD) is very good for movies & TV, while the Sony X90K (LCD) is good.
The Samsung QN90C is very good for watching movies and cinematic TV due to its superior contrast and black uniformity, which enhance dark scene details, and its local dimming feature aids this further. Although the Sony X90K also provides a good experience with the same level of contrast and commendable local dimming, its black uniformity and viewing angles are not as strong as the QN90C's, indicating that dark scenes might not be as richly detailed and the picture quality may vary more from side angles.

The Sony X90K (LCD) and Samsung QN90C (LCD) are both good for sports.
The Samsung QN90C boasts excellent reflection handling and very good motion processing, making it suitable for sports viewership in bright rooms and fast-paced content; however, its viewing angles are not the widest, which could be limiting for group viewing. On the other hand, the Sony X90K excels with its best-in-class motion processing and very good response time that ensure smooth action during sports, but it has only fair reflection handling and may be less ideal for very bright environments.

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."
