If you're on a budget, the TCL S546 could be a better choice as it's typically much less expensive. However, the Vizio Quantum Pro offers slightly better performance in bright rooms and better gaming features, reflecting its upper midrange price. For watching sports, both are comparable, but if gaming is a priority and cost is not an issue, the Vizio Quantum Pro may be more suitable. Both struggle with viewing angles, so if you often watch TV with a large group spread around the room, neither will be perfect. Neither are standout options for watching movies or series in dark rooms. Give Feedback

Although they have very similar scores, PerfectRec considers TCL S546 (LCD) to be good for movies & TV, while the Vizio Quantum Pro (LCD) is only fair.
The TCL S546 is rated better for movies and cinematic TV largely due to its higher contrast and better black uniformity, which are crucial for deep blacks and dark scene details. The Vizio Quantum Pro, while offering wider viewing angles, falls short in black uniformity, making it less suitable for viewing content that benefits from darker, more consistent blacks.

The Vizio Quantum Pro (LCD) and TCL S546 (LCD) are both only fair for sports.
The TCL S546 has a better response time, which is important for fast action in sports, but it has narrower viewing angles and less effective reflections handling than the Vizio Quantum Pro. Conversely, the Vizio Quantum Pro offers wider viewing angles and handles reflections better, making it more suitable for rooms with multiple viewers and bright lighting, although it has slower response time and poorer motion processing, which could lead to more motion blur during fast sports scenes.

The Vizio Quantum Pro (LCD) and TCL S546 (LCD) are both only fair for news, talk, & other TV.
The TCL S546's strength in upscaling and SDR brightness makes it suitable for news and talk shows in various room conditions, while the Vizio Quantum Pro also offers very good SDR brightness but falls short in upscaling which is crucial for viewing lower resolution content such as standard definition TV programs. Both TVs have good colors out of the box and color gamut, with the TCL S546 benefiting from better contrast due to its VA panel, and the Vizio Quantum Pro offering better viewing angles and local dimming, advantageous for wider seating arrangements.

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.
