If you are looking for a more affordable option, the Insignia F20 will cost significantly less than the TCL R648. However, if image quality, particularly in a dark room, and gaming features are more important to you, the TCL R648 might be worth the extra investment. The TCL R648 has a higher refresh rate and miniLED technology, contributing to better picture quality. Keep in mind, though, that the Insignia F20 is suitable for everyday viewing and non-gaming use, especially in well-lit rooms where its lower contrast won't be as noticeable. Give Feedback

The TCL R648 (LCD) is good for movies & TV, while the Insignia F20 (LCD) is poor.
The Insignia F20 falls short in watching movies and cinematic TV primarily because of its poor contrast, local dimming, and black uniformity, which are vital for deep blacks and visual depth in dark scenes. The TCL R648, on the other hand, offers good performance in these areas, enhancing the overall viewing experience with deep blacks and better picture quality, particularly in dark environments.

The TCL R648 (LCD) and Insignia F20 (LCD) are both only fair for sports, though the TCL R648 (LCD) is somewhat better.
The Insignia F20 shows poor performance in response time and motion processing, leading to blurry images in fast-moving sports scenes, and it also struggles with reflections which can be problematic in bright rooms. In comparison, the TCL R648 handles reflections better and has a very good response time, reducing motion blur, yet lacks the wide viewing angles desirable for sports-watching in a group setting.

About Insignia
Insignia is an in-house brand from BestBuy. It offers a range of TV sets that are lower-end and smaller size. They are manufactured in China by Hisense, which is another TV brand. Insignia TVs use Amazon's Fire OS as the smart TV software, providing users with a highly user-friendly 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.
