If you prioritize high-quality picture performance, especially for movies, gaming, and sports, the Sony A90K is a superior choice despite its higher cost. It shines in dark rooms and has excellent overall picture quality, but may not be the best in very bright rooms. Conversely, the TCL S435 is more budget-friendly, but it doesn't perform as well across all content types, particularly struggling with sports and gaming. It's good for cartoons and as a monitor, however, its picture quality in both bright and dark environments is not up to par compared to the Sony. If you're an avid gamer or love to watch movies in the best possible quality and can afford to spend more, the Sony A90K would be a more satisfying purchase. Otherwise, for casual watching and basic needs, the TCL S435 could suffice while saving you money. Give Feedback

"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.
