The TCL R646 offers a good balance of features but at a somewhat lower price. It performs well for gaming and watching movies in a dark room, and it's decent in bright rooms. On the other hand, the TCL R655, while somewhat more expensive, has slightly better overall picture quality and performs exceptionally well for gaming due to its higher refresh rate and lower input lag. However, its performance in bright rooms is only marginally better than the R646. If budget is a constraint and you want good gaming performance and movie watching in darker environments, the R646 could be sufficient. But if you prioritize the best gaming experience and can spend more, the R655 might be the better choice, even though the benefits for other types of content or environments are less pronounced.

wired

Parker Hall | January 2023
"It has an excellent Roku interface, isn’t too expensive, has quantum dots and mini LED backlighting, and looks genuinely fantastic playing everything. If you’re in the market for a new TV, you should still start here. Gamers will like that it has a 120-Hz refresh rate at 4K, which is the maximum that a modern Xbox or Playstation 5 will put out—meaning the smoothest possible gaming and sports viewing in general. We’re no longer in the days of having to spend over $1,000 and spending a few hours on setup for decent black levels and great color accuracy and HDR"

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.
