The TCL R646 offers better overall performance, especially for watching movies and gaming, due to superior picture quality and higher refresh rate, beneficial for fast-moving content. It also has a brighter display, which is ideal for sunny rooms. However, it's more expensive compared to the TCL Q6, which is still a solid choice for general TV watching and casual gaming at a substantially lower price. The TCL Q6 may struggle with fast-paced sports and games due to a lower refresh rate. Neither is the best option for dark room viewing, as both have limitations in black uniformity and local dimming performance. Give Feedback

The TCL R646 (LCD) is very good for gaming, while the TCL Q6 (LCD) is poor.
The TCL R646 is better for gaming because it has a very good response time and good input lag, meaning the display reacts quickly to inputs and minimizes delay, which is crucial for fast-paced gaming. In contrast, the TCL Q6, with a fair response time and best input lag, would be less responsive, making it less suitable for gaming that requires quick reactions.

The TCL R646 (LCD) is very good for cartoons & animation, while the TCL Q6 (LCD) is only fair.
The TCL R646 is rated higher for watching cartoons and animation due to its good color performance right out of the box and a strong color gamut, which ensures bright and diverse colors. On the other hand, the TCL Q6 is seen as fair for the same content because it falls short in delivering colors as accurately and vibrantly initially which are very important for animated content.

The TCL R646 (LCD) is good for news, talk, & other TV, while the TCL Q6 (LCD) is only fair.
The TCL R646 boasts excellent SDR brightness and a very good rating for upscaling, which contributes to a clearer display of standard content and a brighter screen that is useful in well-lit rooms. In contrast, the TCL Q6 has a lower contrast and somewhat poorer upscaling capability, which can lead to less vivid images when watching regular TV programs, especially in bright environments.

The TCL R646 (LCD) is very good for bright room, while the TCL Q6 (LCD) is good.
The TCL R646 is better suited for bright rooms compared to the TCL Q6 as the R646 has higher SDR and HDR brightness, making the picture stand out more in sunlight, and it handles reflections very well, meaning fewer distractions from surrounding light sources. While both TVs have good color-related characteristics, the superior brightness and reflection handling of the R646 make it the preferable option for well-lit environments.

The TCL R646 (LCD) and TCL Q6 (LCD) are both only fair for sports.
The TCL Q6 has adequate motion processing and response time for watching sports, but its poor reflections handling and narrow viewing angles can be limiting in bright rooms or when viewers are seated off to the side. In comparison, the TCL R646 performs better in motion processing and has very good reflections handling, making it more suitable for varied lighting conditions and larger groups, although its gray uniformity is only somewhat better, which is less critical for sports viewing.

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.
