The Sony X90K generally comes at an upper midrange price, costing more than the TCL R646. For a better gaming experience, the Sony X90K is preferred, with better performance in this area. However, if you mostly watch sports, the TCL R646 might not perform as well as the Sony X90K. In bright rooms, the Sony comes out slightly ahead with better handling of reflections, but the TCL is also capable in well-lit environments. For watching movies, both are good options, but if the price is a major consideration, you might lean towards the TCL since it is less expensive while still offering a good quality picture. Do keep in mind the differences in sound quality and whether you're likely to use an external speaker system or rely on the TV's built-in speakers, as this could influence your decision. Both TVs support HDR and have 4 HDMI ports, but neither has great built-in speakers, so you may want to consider a separate sound system for the best audio experience. Give Feedback

The Sony X90K (LCD) is good for sports, while the TCL R646 (LCD) is only fair.
The Sony X90K offers better motion processing, which is pivotal for the smooth display of fast-paced sports action, and its response time is rated higher, ensuring crisper images during fast movements. In contrast, the TCL R646, despite handling reflections better, which is advantageous in bright rooms, falls short in motion processing and has a narrower viewing angle, making it less ideal for sports watching where fast action and multiple viewer positions are common.

The Sony X90K (LCD) is very good for news, talk, & other TV, while the TCL R646 (LCD) is good.
The Sony X90K delivers exceptional upscaling of non-4K content and maintains very good brightness for viewing in standard dynamic range, which is important for displaying news and talk shows clearly; however, while the TCL R646 also provides good performance in these areas, it may have slightly less impressive out-of-the-box color accuracy and narrower color gamut compared to the Sony X90K, affecting the initial viewing experience. Additionally, aspects like local dimming and contrast, where both TVs do well, contribute to clear on-screen images, but the Sony may have a slight edge in producing deeper blacks and more uniform brightness across the screen.

"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."

About Sony
Sony stands as a highly experienced and widely trusted TV manufacturer, earning a reputation that surpasses all others. A Japanese company, Sony has been making TVs for far longs than it has been making Playstation game consoles. Sony's high-end TVs are often regarded as the ultimate choice for videophiles, representing the epitome of quality, albeit at a premium price point. Renowned for their advanced and precise motion handling, as well as their cutting-edge local dimming algorithms, Sony consistently delivers unparalleled performance in these areas. They include Google TV software with all their TV sets, which grants access to the largest selection of apps available and they also include Bravia Core which is a movie streaming platform specifically for Sony TVs that offers higher picture quality by using more bandwidth.
About TCL
TCL, the highly recognizable TV brand from China, has firmly established itself as the second-largest manufacturer in terms of sales volume. Renowned for striking an impressive balance between affordability, picture quality, and design, TCL TVs deliver a compelling overall package. While they have traditionally excelled in the low-end and midrange TV segments, TCL has recently made remarkable strides in the realm of high-end televisions, introducing impressive models that rival top competitors. Most TCL TVs use Roku software which is very user friendly and easy to use, but they have a few other models that use Google TV which has the largest app selection, but is not as user friendly as Roku.
