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.

The TCL S555 (LCD) and TCL R646 (LCD) are both good for movies & TV.
The TCL R646 excels in watching movies and cinematic TV due to its high contrast, effective local dimming that enhances black uniformity, and respectable color reproduction immediately upon use. In contrast, while the TCL S555 also offers strong black uniformity and out-of-the-box colors, it may not handle different shades of gray as uniformly and its viewing angles are limited, making it less ideal for rooms with wide seating arrangements.

The TCL R646 (LCD) and TCL S555 (LCD) are both only fair for sports.
The TCL R646 has a very good response time which is beneficial for watching fast-moving sports, but its reflections handling is rated only as very good, which could be a concern in very bright rooms. On the other hand, the TCL S555, while also having good response time, suffers more from reflections due to a poor rating in reflections handling, making it less suitable for brightly lit environments; however, both TVs have limited viewing angles which could affect the view from off-center positions.

"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.
