The TCL R648 is a premium-priced TV with features such as a high gaming score, great for dark and bright rooms, and excellent motion processing capabilities. It has miniLED technology for better contrast and brightness, supports Dolby Vision and has superior sound quality with great speakers. Conversely, the TCL S555 is priced lower and offers good overall picture quality with a high contrast ratio, but it performs less well in gaming and bright rooms, and has a lower sound quality. If your budget allows, and you prioritize gaming and overall brightness, including a better audio experience, the TCL R648 would be a superior choice. However, if you want to save money and still enjoy good picture quality for movies and general content, the TCL S555 could be very satisfactory. Keep in mind that the TCL S555 does not have great speakers, which could impact your viewing experience if you rely solely on the TV's built-in audio. Give Feedback

"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.
