The Samsung S90C is a premium OLED TV which provides outstanding overall picture quality, great for gaming due to low input lag and rapid response time, and offers perfect blacks for a superior dark room experience. However, it may not be as bright in sunny rooms compared to some other models. The Sony X90K is a more affordably priced upper midrange LCD TV that has good picture quality and performs well for gaming too. Its screen may not deliver the same level of deep blacks as an OLED but has a higher brightness, making it better suited for bright rooms. Consider the Samsung S90C if picture quality, especially for gaming and dark room viewing, is your priority and you're okay with a higher cost. If you're looking for a more budget-friendly option that performs better in bright rooms, the Sony X90K could be a good fit. Give Feedback

Although they have very similar scores, PerfectRec considers Samsung S90C (OLED) to be excellent for news, talk, & other TV, while the Sony X90K (LCD) is very good.
The Samsung S90C excels in upscaling lower resolution content and provides very good SDR brightness, which is crucial for clear viewing in programs that typically broadcast in less than 4K, such as news and talk shows. On the other hand, while the Sony X90K also demonstrates very good performance in these areas, it doesn't quite match the Samsung in upscaling and SDR brightness but compensates with good color reproduction and contrast, contributing to a pleasing image for everyday TV programs.

"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."
