If you prioritize gaming performance and a smooth experience with fast-moving content, the TCL R646 might be the better choice due to its higher refresh rate. It is also brighter, which is beneficial if you watch TV in a bright room. However, its higher price reflects these advantages. On the other hand, the Vizio M-Series has a lower price and is quite well-rounded, with good performance for watching movies, animated content, and news. It's a solid choice if you're on a budget and looking for a versatile TV, but it may not perform as well in very bright rooms or for gaming purposes. Give Feedback

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.

About Vizio

Vizio is an American company. While they initially gained recognition for offering budget-friendly TVs, they have successfully expanded their product lineup to include high-end options as well. They manufacture TVs primarily in Mexico, China, and Vietnam. Similar to many Korean TV brands, Vizio developed its own smart TV software called SmartCast. In the past, SmartCast was not the best smart TV software, but it has evolved so that it is now good for using your TV and connecting to streaming services.
