The TCL R646 offers better overall picture quality, enhanced gaming, and sports viewing experiences, and performs well in both dark and bright rooms. It also provides more advanced features like local dimming, higher brightness, and a wider color range. It's a better choice if you prioritize gaming or want a TV that can handle various lighting conditions effectively.
On the other hand, the TCL S450G is more budget-friendly and still performs moderately well, especially considering its price point. It could suit you if you're looking for a cost-effective option for casual viewing, like watching news or animated content, and don't need the top gaming or bright room performance. Give Feedback

The TCL R646 (LCD) and TCL S450G (LCD) are both only fair for sports.
The TCL R646 has better response time and motion processing compared to the TCL S450G, which means it handles fast-moving scenes and action-packed sports with less blur, making it a better choice for sports enthusiasts. However, both TVs have similar challenges with viewing angles and reflections; thus, neither is ideal for rooms with wide seating arrangements or lots of light.

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.
