The TCL R646 is generally better for a range of content including movies, gaming, and use in bright rooms. It comes at a midrange price and offers features such as a higher contrast, better brightness in both SDR and HDR, as well as local dimming which improves dark room performance. However, the TCL S446 is priced more affordably and could suffice if your budget is tight and your viewing habits are more casual, such as watching news or cartoons. The S446 may not perform as well in very bright or very dark rooms. If gaming is a priority, you would benefit more from the R646's higher gaming performance. If you need wide viewing angles, the S446 has an edge, but it falls behind in other picture quality aspects. Give Feedback

The TCL R646 (LCD) is very good for gaming, while the TCL S446 (LCD) is poor.
The TCL R646 excels in gaming due to its very good response time and low input lag, paired with a high refresh rate of 120Hz, offering smoother motion and a more responsive gaming experience. In contrast, the TCL S446, while having very good input lag, is held back by just fair response time and a lower refresh rate of 60Hz, which means it might not be as smooth or quick to react during fast-paced games.

The TCL R646 (LCD) is very good for cartoons & animation, while the TCL S446 (LCD) is only fair.
The TCL R646 features better out-of-the-box colors and a wider color gamut, which enhances the vibrancy and variety of hues when watching animation, but also displays a higher contrast and brighter SDR image making it suitable for various lighting conditions.

The TCL R646 (LCD) is good for news, talk, & other TV, while the TCL S446 (LCD) is only fair.
The TCL R646 is better for watching news, talk shows, and other TV programs due to its excellent upscaling capabilities and brighter screen for SDR content, meaning it can more effectively improve lower resolution content and remain more visible in various lighting conditions. In contrast, the TCL S446, while offering fair upscaling and color performance out of the box, lacks local dimming and has a lower contrast ratio, which can affect picture depth and detail clarity, particularly in darker scenes.

The TCL R646 (LCD) is very good for bright room, while the TCL S446 (LCD) is poor.
The TCL R646 excels in bright rooms due to its excellent SDR brightness and very good reflections handling, making it more suitable for environments with a lot of light. On the other hand, the TCL S446 has poor HDR brightness, which in combination with its only good reflections handling, renders it less capable of delivering an optimal viewing experience in bright conditions.

The TCL R646 (LCD) and TCL S446 (LCD) are both only fair for sports.
The TCL R646 has a faster response time and better motion processing, which are critical for watching sports smoothly; however, its narrow viewing angles and fair reflection handling could be an issue in brighter rooms or larger gatherings. Meanwhile, the TCL S446 offers wider viewing angles, making it a better option for watching with a group, but its slower response time and weaker motion processing might not handle fast-paced sports as effectively.

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.
