The Sony X90K is less expensive and offers more stand positioning options which may be useful for different furniture configurations. Conversely, the Sony X90L, while slightly more expensive, includes voice command functionality and generally has better picture and sound quality. If you have a bright room, the X90L with its slightly better brightness would be more beneficial, but for a darker room or if budget is a concern, the X90K is still a robust choice. Give Feedback

The Sony X90L (LCD) and Sony X90K (LCD) are both very good for cartoons & animation, though the Sony X90L (LCD) is somewhat better.

The Sony X90L (LCD) and Sony X90K (LCD) are both very good for bright room, though the Sony X90L (LCD) is somewhat better.
The Sony X90K has very good SDR and HDR brightness, effectively combating glare in bright rooms and displays deep blacks due to its high contrast. On the other hand, the Sony X90L outshines in SDR brightness for an even better bright room experience but falls short in reflection handling compared to the X90K, which can affect viewing when faced with direct light sources.
The Sony X90L (LCD) and Sony X90K (LCD) both have good picture quality.

How the Sony X90K (LCD) and the Sony X90L (LCD) compare to other TVs
"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."
