If you prioritize picture quality, especially in darker rooms, and are okay with a smaller screen, the Sony A90K with its OLED panel will deliver deep blacks and high image fidelity. However, if you prefer a larger display and plan on watching content in bright rooms, the TCL R648's brighter miniLED FALD VA screen might be more suitable despite being the more expensive option. Keep in mind that the TCL also offers a higher resolution, which could benefit you if you plan on watching native 8K content, while the Sony has the advantage in terms of overall picture quality for most content, which is usually in 4K or lower resolutions.

The Sony A90K (OLED) is excellent for movies & TV, while the TCL R648 (LCD) is good.
The Sony A90K OLED TV offers perfect black uniformity and excellent contrast, which is essential for viewing in dark rooms, making it excellent for watching movies and cinematic TV. The TCL R648, while having a good full-array local dimming feature that improves contrast, doesn't match the black uniformity and contrast of the OLED, which is why it's considered good rather than excellent for the same content.

The Sony A90K (OLED) is excellent for sports, while the TCL R648 (LCD) is only fair.
The Sony A90K excels at watching sports due to its outstanding motion processing and wide viewing angles, which ensure a clear and consistent picture even from different seating positions. In contrast, the TCL R648, while providing a very good response to motion, falls short with its handling of reflections and limited viewing angles, which could affect viewing experience in brightly lit rooms and for viewers sitting off to the side.

The Sony A90K (OLED) and TCL R648 (LCD) are both very good for gaming, though the Sony A90K (OLED) is somewhat better.
The Sony A90K OLED TV has an excellent response time, ensuring quick transitions between different images which is vital for gaming.

The Sony A90K (OLED) is very good for news, talk, & other TV, while the TCL R648 (LCD) is good.
The Sony A90K OLED TV is better for viewing in rooms with controlled lighting due to its excellent upscaling and lower SDR brightness, making it ideal for watching news and talk shows where image quality is key. In contrast, the TCL R648 with its superior SDR brightness and good upscaling would be a better choice for rooms with more ambient light, although it might not handle lower resolution content as cleanly as the Sony.

In contrast, the TCL R648 LCD TV shines with excellent SDR brightness and very good reflections handling, ensuring it performs better in brightly lit spaces despite a slightly lower contrast compared to the Sony A90K.

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.
