If you're looking for a more affordable option and can compromise on picture quality, the Insignia F20 could be suitable for basic TV watching in a bright room. However, the Sony X90K, while more expensive, offers significantly better performance across most content, including movies, sports, and gaming. It's especially better in both dark and bright rooms and has higher quality sound. For gaming, the Sony provides a superior gaming experience due to its responsiveness and higher refresh rate capabilities. If you often watch high dynamic range (HDR) content, the Sony X90K's support for advanced HDR formats like Dolby Vision will enhance your viewing experience. On the other hand, the Insignia does not support these premium features and also falls short in picture and sound quality. 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."
