If you're on a budget, the TCL S450R offers a more economical choice, but it performs poorly for gaming and high dynamic range (HDR) content, which may not be ideal if you enjoy vibrant picture quality. The TCL R648 is a premium option with better clarity and contrast, enhanced HDR capabilities including Dolby Vision, and superior gaming performance with a higher refresh rate. However, the R648 will cost significantly more. Both models struggle with wide viewing angles, meaning the picture quality may degrade if you're not sitting directly in front of the TV. The R648's miniLED technology improves brightness and dark room performance, which makes it a better choice for varied lighting conditions in your watching area. In conclusion, if you can afford the higher price, the R648 provides a more robust viewing experience across different types of content, along with better features for gaming and HDR viewing.

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.
