Insignia F50 Series 4K Fire TV vs LG Nano 4K UHD AI NU70 Smart TV

The Insignia F50 is the better pick for most people deciding between these two. It gives you a bigger 50-inch screen, three HDMI ports, HDR10, DTS Virtual-X sound and eARC, and it runs Fire TV with Alexa built into the remote. The LG NU70 is a smaller 43-inch set with only two HDMI ports, but it carries LG's name and webOS-style smart platform with both Google Assistant and Alexa support. Owners rate the Insignia slightly higher on average, though from far more ratings.

• Choose the Insignia F50 if you want the larger screen, more HDMI inputs and Fire TV with an Alexa voice remote.
• Choose the LG NU70 if you prefer a smaller 43-inch set and LG's smart platform with both Google Assistant and Alexa.
