The Sony X90K is at an upper midrange price and generally performs better across the board, especially for gaming, watching movies and series, and in brighter rooms. It provides good reflection handling, better motion processing, and has a higher refresh rate which is great for gaming. If you value a more immersive experience with higher picture and sound quality, the Sony could be a great choice. On the other hand, the TCL S435 is a budget-friendly option and still offers decent performance for casual watching, particularly for cartoons and animation. However, it has less impressive contrast, brightness, and overall picture quality. It also lacks local dimming, which can affect the dark room viewing experience. If budget is a priority and your viewing habits are not demanding, the TCL S435 could serve you well. But if you're willing to invest more for a better all-around experience and particularly value gaming and bright room performance, the Sony X90K would be the superior option. Give Feedback

The Sony X90K (LCD) is good for movies & TV, while the TCL S435 (LCD) is only fair.
The Sony X90K offers better movie and cinematic TV viewing compared to the TCL S435 due to its very good contrast, effective local dimming, and strong black uniformity, which enhance the viewing experience in darker scenes. Conversely, the TCL S435, despite having excellent colors out of the box, falls short with its lack of local dimming and poorer black uniformity, making it less suitable for viewing content where dark scene performance is crucial.

The Sony X90K (LCD) is good for sports, while the TCL S435 (LCD) is poor.
The Sony X90K is better for sports due to its superior motion processing which decreases blur in fast-moving scenes, and its handling of reflections is more effective, making it easier to watch in various lighting conditions. The TCL S435, on the other hand, struggles with motion due to slower response time, and reflections might be more distracting, reducing visibility especially in bright rooms.

The Sony X90K (LCD) is very good for news, talk, & other TV, while the TCL S435 (LCD) is poor.
The Sony X90K excels in upscaling and has very good SDR brightness, meaning it can make lower resolution content from news or talk shows look better and remain visible in well-lit rooms. On the other hand, the TCL S435 struggles with upscaling and has poor SDR brightness, which could result in less clear images and difficulty watching in bright rooms.

The Sony X90K (LCD) is very good for bright room, while the TCL S435 (LCD) is poor.
The Sony X90K performs well in bright rooms thanks to its ability to get very bright in SDR and HDR, which counters glare and maintains visibility in sunlight, and it handles reflections adequately. On the other hand, the TCL S435 struggles in bright rooms due to its poor brightness in both SDR and HDR, and it handles reflections poorly, which can result in a washed-out image when there's a lot of ambient light.

"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."

"The TCL 4-Series is so inexpensive and capable you might start to question why there are any multithousand-dollar TVs at all. The 4-Series setup is intuitive and easy. If you're just looking for an easy-to-use TV with decent picture, this is an excellent place to start."

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.
