If you often play video games and want quicker response times with smoother motion, the Samsung Q70A would be a better option as it has a higher gaming score and supports a higher refresh rate. For watching movies in a dark room, the TCL S450F would impress with its excellent black uniformity, but the Samsung Q70A provides a very good contrast and better local dimming which can enhance the viewing experience. When viewing content in a bright room, the Samsung Q70A's higher bright room score means it will handle reflections and maintain visibility better than the TCL S450F. However, if budget is a primary concern, the TCL S450F offers a fair overall picture quality at a lower price point, making it a cost-effective choice. The TCL also has voice command features for accessibility, which the Samsung does not have. Keep in mind that the Samsung Q70A is a 2021 model with more advanced features like a 120Hz screen and better color reproduction, making it a more future-proof investment if you're looking for longevity and higher performance in a variety of content viewing situations.

About Samsung
Samsung, a South Korean electronics manufacturer, holds the title of being the largest global TV vendor in terms of units sold. They offer a diverse lineup of TV products that cater to various budget ranges. A notable achievement in recent years is the development of Quantum Dots, a technology that enhances color reproduction, resulting in richer and more vibrant hues. Samsung TVs are well-regarded for their high manufacturing quality and user-friendly software, making them an excellent choice for consumers seeking an intuitive viewing 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.
