If you watch a lot of movies or sports in darker rooms, the Sony X90K provides better performance, particularly with its higher dark room score, thanks to better local dimming and higher contrast. It's also slightly better for playing games. However, if you're looking for a more budget-friendly option, the Samsung Q70A is somewhat less expensive and still offers good gaming performance and brightness in well-lit rooms, although it falls short in dark room viewing quality. Both TVs support similar HDR formats, but if you require Dolby Vision for watching movies, the Sony X90K supports it unlike the Samsung Q70A. On the other hand, the Samsung Q70A supports HDR10+ which the Sony X90K does not. Sound quality is also better in the Sony X90K, but neither TV has particularly great speakers, so you may want to consider a soundbar regardless of your choice. In summary, the Sony X90K is generally better in terms of overall picture quality, and especially for darker rooms, but it comes at a higher price compared to the Samsung Q70A. Give Feedback

The Sony X90K (LCD) is good for movies & TV, while the Samsung Q70A (LCD) is only fair.
The Sony X90K is considered better for movies & cinematic TV mainly because of its superior local dimming feature which enhances contrast and black uniformity, providing a better movie-watching experience with deeper blacks and more defined shadows. Meanwhile, the Samsung Q70A has a higher contrast ratio but lacks local dimming, which can lead to less impressive black levels and a less captivating experience in dark scenes; its viewing angles and reflection handling are also rated lower, impacting its performance in rooms with ambient light.

Although they have very similar scores, PerfectRec considers Sony X90K (LCD) to be good for sports, while the Samsung Q70A (LCD) is only fair.
The Sony X90K is better than the Samsung Q70A for sports because the Sony has superior motion processing which is crucial for fast-action scenes, and it handles reflections better which is important in bright rooms. While both have similar viewing angles, essential for a group watching, the Samsung falls short in the aforementioned areas, affecting its overall sports viewing quality.

"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."
