If you frequently play video games and want a better gaming experience with faster response, the TCL Q7 would suit you well. However, the TCL S450F has an excellent black uniformity for those who enjoy watching content in a dark room, such as movies, and it comes at a lower cost. If screen reflections and viewing angle are vital to you, neither of these models excels in those areas. For a general television experience with a balance of price and performance, including watching the news, TV shows, and sports content, the TCL Q7 offers a better overall picture quality and is likely worth the extra investment, unless budget is a primary concern.

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.
