The Sony X90K (LCD) is very good for news, talk, & other TV, while the Samsung Q80C (LCD) is good.
The Sony X90K excels in upscaling which enhances lower resolution content making it very good for watching news and talk shows, alongside its excellent SDR brightness that ensures the picture is clear and bright. In comparison, the Samsung Q80C is good in the same areas but does not reach the performance levels of the Sony, notably in upscaling and colors out of the box, which might slightly affect its ability to display crisp and vibrant content for the same types of programming.

Although they have very similar scores, PerfectRec considers Sony X90K (LCD) to be good for sports, while the Samsung Q80C (LCD) is only fair.
The Sony X90K outperforms the Samsung Q80C when watching sports primarily because it has better motion processing capabilities and manages reflections more effectively. While both TVs have similar response times and viewing angles, the Samsung Q80C is hindered by its poor handling of reflections and fair motion processing compared to the Sony X90K's fair reflection handling and good motion processing.

"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."
