If you prefer a TV that's less expensive and provides good overall quality with strong performance in gaming, the Sony X90J could be the right choice. However, it doesn't perform as well in very bright rooms compared to the TCL R648. On the other hand, if you're willing to invest more in a TV, the TCL R648 might suit you with its slightly better performance in well-lit environments and higher brightness in HDR content. Keep in mind that it's most likely to cost more than the Sony X90J and has a lower score when it comes to watching sports. Give Feedback

The Sony X90J (LCD) is good for sports, while the TCL R648 (LCD) is only fair.
The Sony X90J is better for watching sports due to its superior motion processing which ensures smoother playback during fast action and its better response time which reduces motion blur, both key for sports where speed and clarity are crucial. On the other hand, the TCL R648, despite having good response time, falls short in motion processing and also has slightly worse handling of reflections and a narrower viewing angle, which can be disadvantages in brightly-lit environments and when watching with a large group.

The Sony X90J (LCD) is very good for news, talk, & other TV, while the TCL R648 (LCD) is good.
The Sony X90J excels in upscaling and SDR brightness which are crucial for clear viewing in TV programs and news, ensuring detailed images in various content resolutions and visibility in most lighting conditions; it also boasts better colors out of the box for a vibrant picture. On the other hand, the TCL R648 provides good performance for watching TV programs and news with its competent upscaling and SDR brightness capabilities, but its colors out of the box and overall contrast may not be as superior as the Sony X90J, which affects the immediate visual impact.

The TCL R648 (LCD) is very good for bright room, while the Sony X90J (LCD) is good.
The TCL R648 excels in brightly lit rooms partly because it has excellent SDR brightness and handles reflections very well, making it easier to see the picture without glare. On the other hand, while the Sony X90J provides a very good SDR brightness for a well-lit room, it doesn't manage reflections as effectively, which could affect viewing when there are a lot of light sources around.

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.
