The Sony X85J is often significantly more expensive and may not perform as well in a dark room. However, it delivers a better experience for sports content.

If budget is a concern and you game often or watch TV in bright rooms, the TCL may be the more suitable option. Conversely, if you're frequently watching sports and are less sensitive to price, the Sony might be the better choice. Give Feedback

The TCL R646 (LCD) is good for movies & TV, while the Sony X85J (LCD) is only fair.
The TCL R646 offers better performance for watching movies and cinematic TV compared to the Sony X85J, primarily due to its superior contrast, effective local dimming, and better black uniformity, which are crucial for dark room viewing. While the Sony X85J has decent picture quality, its lack of local dimming and poorer black uniformity mean it won't provide as immersive an experience in darker scenes commonly found in movies and cinematic content.

The Sony X85J (LCD) is very good for news, talk, & other TV, while the TCL R646 (LCD) is good.
The Sony X85J performs well for watching news and TV programs largely due to its good upscaling of lower-resolution content and commendable SDR brightness, making it suitable for most lighting conditions. On the other hand, the TCL R646 also does well with content like news due to its superior SDR brightness, which allows it to handle very well-lit rooms, but its upscaling is not as proficient as the Sony X85J's, making lower-resolution content look less refined.

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.
