TCL S4 65" 4K Roku TV vs VIZIO Quantum 4K QLED 58" TV

The VIZIO Quantum is the better picture for the money in this pair: QLED with Dolby Vision beats the TCL S4's plain LED panel with no local dimming, and the 4.7 rating, though from far fewer owners, backs that up. The TCL wins on size, Roku's app selection, four HDMI ports and a long track record with 45,000-plus ratings. Buy the VIZIO for movies and HDR in a smaller room; buy the TCL for a bigger screen, more inputs and the simplest smart interface.

• Choose the TCL S4 if you want the larger 65-inch screen, four HDMI inputs and Roku's clean interface with AirPlay and all three voice assistants.
• Choose the VIZIO Quantum if picture quality matters most and you want QLED color, Dolby Vision and Wi-Fi 6 in a slightly smaller set.
