If you're looking for a TV that offers better black uniformity and is slightly less expensive, the TCL S450R could be the right choice, particularly if you enjoy watching content that benefits from deeper blacks, like movies in a dark room. However, the Amazon Omni Series provides better sound quality and slightly better upscaling of lower resolution content, which might be preferable if you often watch standard definition channels or DVDs. Both TVs have their strengths for watching content in a bright room, but neither is outstanding in this aspect. For gaming or watching sports, both models offer a fair performance, but they might not be the best option if these are your primary activities. The TCL's best in class input lag score also gives it an advantage for gaming, but this is balanced by its poor motion processing. Keep in mind that both are budget models, so you may need to manage your expectations regarding overall picture quality and HDR performance. Give Feedback

"If you want a competent budget screen with some handy features, the Amazon Omni TV delivers an experience that punches well above its price tag. You’ll also get the benefit of Fire TV’s new UI right out of the box. It’s clean and simple to understand, plus it puts content first. In the picture-quality department, the Amazon Omni is a surprising star among some of its dimmer, less colorful rivals."

About Amazon
Amazon, the largest online retailer in North America, has forged partnerships with TCL and Hisense to produce white-label TVs incorporating their Fire OS software. These Amazon-branded TVs typically compete in the low-end and mid-range segments, offering compelling price points. Leveraging their strong reputation, Amazon has swiftly built brand trust in the TV market despite being relatively new to it. To enhance their popularity, these TVs integrate features from the Amazon ecosystem, including Alexa, providing users with a seamless and interconnected TV experience.
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.
