If your priority is overall picture quality for a variety of content, including movies, sports, and gaming, and you don't mind spending more, the Sony X85K is a better choice. However, if you're looking to save money and need a TV that is very good at displaying cartoons and animation or offers voice commands for accessibility, then the TCL S450F could be a suitable option, keeping in mind that its performance for sports, movies, and gaming is inferior to the Sony. Neither TV is ideal for very bright rooms, but the Sony is likely to handle them better, though with some limitations in a dark room. For gamers, the Sony provides a good gaming experience and supports advanced gaming features, while the TCL is poor in this regard. Sound quality on both is fair, so consider a soundbar for better audio. If connectivity is key, both have 4 HDMI ports, but the Sony benefits from a higher refresh rate, better motion processing, and better upscaling of lower resolution content. Give Feedback

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.
