If price is your primary concern, the TCL S450R is the more cost-effective option and it supports Dolby Vision for HDR content, which the S455 does not. The S450R also has HGiG support for gaming, which the S455 lacks, making it a slightly better choice if you're interested in gaming. However, both TVs have similar picture quality and are limited by poor local dimming and HDR brightness, meaning neither is ideal for very bright rooms or achieving the best HDR experience. They both offer a 4k @ 60Hz @ 4:4:4, which is good for general use and some gaming. If having the latest model and voice command functionality are important to you, the S450R has those features, while the S455 does not. Overall, unless the S455's additional features are must-haves for you, the S450R seems to offer a slightly better value. Give Feedback

"A highly affordable but reliably kitted-out 4K Roku TV that, while far from perfect, still punches above its price and delivers a great user experience. If you want to soup up movie night for a bargain, the 4-Series won’t let you down. You may never need to plug in a set-top box or streaming device."

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.
