If you're interested in a better experience for sports or gaming, and you have a bit more to spend, the TCL R646 could be a solid choice due to its higher refresh rate. However, it may not be the best for bright rooms. On the other hand, the TCL S555 is more budget-friendly and still offers decent performance for watching movies and series, but may not be as suitable for sports and gaming due to a lower refresh rate and a lower performance in bright environments.

Caleb Denison | December 2022
"It looks great out of the box and the picture quality it is rock-solid for the price. (...) What really makes this a decent gaming TV, though, is the very low input lag. (...) But if you want to save a little money, the TCL S555 strikes a great balance between cost and performance – the kind of performance that’s impressive enough to deliver some wow to your eyes. (...)"

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.
