The TCL S435 (LCD) is only fair for movies & TV, while the Sony X77L (LCD) is poor.
The Sony X77L falls short for movies and cinematic TV due to its less effective contrast, lack of local dimming, and inferior black uniformity, which can make dark scenes in films look washed out and lack depth. On the other hand, the TCL S435, while also having limitations in these areas, offers somewhat better performance with more consistent colors out of the box and slightly superior gray uniformity, which contributes to a fairer viewing experience in similar content.

The Sony X77L (LCD) is only fair for sports, while the TCL S435 (LCD) is poor.
The Sony X77L has better motion processing, crucial for smooth fast action in sports, and handles reflections more effectively than the TCL S435, making it more suitable for well-lit rooms where glare could be an issue. In contrast, the TCL S435 has significantly poorer motion processing and is less effective at handling reflections, which could lead to a subpar sports watching experience, especially in brighter environments.

The TCL S435 (LCD) is good for cartoons & animation, while the Sony X77L (LCD) is only fair.
The TCL S435 is considered good for watching cartoons & animation as it delivers excellent colors straight out of the box, which is crucial for animated content with vibrant hues. In contrast, the Sony X77L, while offering very good out-of-the-box colors, falls short with a poor color gamut, limiting the range of colors it can display, and this might not be as appealing for colorful animated content.

Although they have very similar scores, PerfectRec considers Sony X77L (LCD) to be only fair for news, talk, & other TV, while the TCL S435 (LCD) is poor.
The Sony X77L delivers better upscaling of lower resolution content like standard TV programs and has higher SDR brightness, making it more suitable for viewing in well-lit environments. In contrast, the TCL S435 has poorer upscaling and SDR brightness, which results in it being less ideal for watching news and TV shows, especially in bright rooms.

Although they have very similar scores, PerfectRec considers Sony X77L (LCD) to be only fair for bright room, while the TCL S435 (LCD) is poor.
The Sony X77L delivers a better bright-room viewing experience than the TCL S435 due to its higher SDR brightness and more effective handling of reflections, which are critical in well-lit environments. Additionally, the X77L's better color volume and gamut provide superior image quality in most content, even though its contrast isn't as high as the S435's, which matters less in a bright room.

"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.
