For a sunny room, the Sony X90J may not perform as well as the TCL R646, which boasts better brightness capabilities. The Sony, however, has a track record of quality control and assurance, indicative of potentially higher build quality and reliability. If gaming is a priority, both TVs have good performance, but for those who value movie watching, specifically in dark rooms, the Sony has a slight edge. The TCL tends to be more affordable, so if budget is a key factor, it offers a compelling value proposition. Sound quality is generally not the selling point for either set, so considering a separate sound system might be beneficial. Both TVs support a range of HDR formats but the TCL does include HDR10+ which the Sony lacks. Give Feedback

The Sony X90J (LCD) is very good for news, talk, & other TV, while the TCL R646 (LCD) is good.
The Sony X90J is very good for watching news and TV programs due to its high performance in upscaling lower resolution content and delivering very good SDR brightness. On the other hand, the TCL R646 is also suited for such content with excellent SDR brightness and good upscaling, but expect colors out of the box, color gamut, and local dimming to be less optimal than the Sony, albeit still capable.

The TCL R646 (LCD) is very good for bright room, while the Sony X90J (LCD) is good.
The TCL R646 outperforms the Sony X90J in bright room viewing primarily because it has excellent SDR brightness and very good reflection handling, making it more suitable for brighter environments. On the other hand, the Sony X90J, while still good for bright rooms with its very good SDR brightness, is less adept at minimizing glare due to its poorer reflections handling.

The Sony X90J (LCD) and TCL R646 (LCD) are both good for movies & TV.
The Sony X90J provides a good cinematic experience with its strong contrast, effective local dimming, and impressive black uniformity, which enhance movie-watching in darker environments; however, it has limited viewing angles and poorer performance in bright rooms due to reflections. Conversely, the TCL R646 offers a similar movie-centric performance with slightly better black uniformity and contrast, alongside decent colors out of the box and color volume, but it shares the Sony's viewing angle limitations and similarly struggles with reflections in well-lit spaces.

Although they have very similar scores, PerfectRec considers Sony X90J (LCD) to be good for sports, while the TCL R646 (LCD) is only fair.
The Sony X90J is preferred for watching sports due to its excellent motion processing which smooths out fast action, while the TCL R646 has lower performance in motion processing which may result in blurrier fast motion. Additionally, the Sony handles reflections poorly, which can be bothersome in a bright room, whereas the TCL has very good reflection handling, making it more suitable for well-lit environments.

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.
