If you prioritize gaming and are willing to spend more, the TCL QM8 may be a better option due to its higher performance in that area. However, for watching sports, both TVs are quite similar, with only a slight edge to the R646. The QM8 provides a better experience in bright rooms and has an overall higher picture quality, but it comes at a higher price. For movies and series, the QM8 slightly outperforms the R646. If price is a concern, the R646 offers good quality for movies, TV shows, and gaming, but with a bit less brightness and picture quality compared to the QM8. Both TVs support similar features like Dolby Vision and use similar screen technology (miniLED FALD VA), so the main differences are in performance metrics where the QM8 generally outperforms, but it costs more.

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.
