The TCL QM8 excels in gaming performance and dark room viewing, making it especially suitable for gamers and movie enthusiasts who prefer a cinematic experience. It offers better overall picture quality, higher brightness for both SDR and HDR content, as well as superior color accuracy and consistency. Its mini-LED technology can enhance contrast and make for a more immersive viewing experience. On the other hand, the Vizio Quantum Pro may be preferred for general quality at a slightly lower image fidelity. It offers good performance for a variety of content, although it may not be as bright or as good in dark room settings as the TCL QM8. The Quantum Pro also has a satisfactory range of features, but with slightly lower performance scores in key categories compared to the TCL QM8. Both TVs are similarly priced and support major HDR formats, with a variety of accessibility features. Your choice should depend on whether you prioritize gaming and darker-room viewing (TCL QM8) or are more interested in a balanced performance across different types of content (Vizio Quantum Pro).

The TCL QM8 (LCD) is very good for movies & TV, while the Vizio Quantum Pro (LCD) is only fair.
The TCL QM8 stands out in movie and cinematic TV viewing primarily due to its superior contrast, local dimming, and black uniformity, which are crucial for deep blacks and high image depth, while the Vizio Quantum Pro, though fair, falls short in these very important aspects. Additionally, the TCL QM8 offers better colors out of the box and color volume, factors that enhance the overall picture quality, whereas the Vizio Quantum Pro, despite being rated very good in color volume, doesn't match the TCL's performance in these somewhat important factors.

The TCL QM8 (LCD) is very good for cartoons & animation, while the Vizio Quantum Pro (LCD) is good.
The TCL QM8 excels in displaying cartoons and animation with more accurate colors straight out of the box and a wider color gamut, ensuring vibrant and diverse colors. Compared to the Vizio Quantum Pro, which also has a very good color gamut but doesn't perform as well with factory color settings, making it slightly less optimal for colorful content such as animations.

The TCL QM8 (LCD) is best in class for bright room, while the Vizio Quantum Pro (LCD) is good.
The TCL QM8 outshines the Vizio Quantum Pro in bright rooms largely due to its higher SDR and HDR brightness as well as better handling of reflections, making it better at overcoming ambient light. While both TVs are proficient in color performance and handling contrast, the Vizio Quantum Pro's lower brightness levels and reflection handling make it less ideal than the TCL QM8 in well-lit environments.

The TCL QM8 (LCD) and Vizio Quantum Pro (LCD) are both only fair for sports.
The TCL QM8 is noted for its good response time, which is crucial for watching fast-moving sports, but it has limited viewing angles, which can be a drawback if you have a wide seating arrangement. On the other hand, the Vizio Quantum Pro offers better viewing angles, making it a more suitable option for group viewing, but its motion processing is not as competent, which means you might notice more blur during fast action scenes.

The TCL QM8 (LCD) and Vizio Quantum Pro (LCD) are both only fair for news, talk, & other TV.
The TCL QM8 performs exceptionally in SDR brightness, making it suitable for bright rooms, but its upscaling quality is limited, affecting the clarity of lower resolution content like cable TV. On the other hand, the Vizio Quantum Pro displays fair colors out of the box without the need for calibration and achieves good SDR brightness, but its local dimming performance is less impressive, which can affect contrast in dark scenes.

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.
