Amazon Fire TV 65" Omni Series vs Pioneer R851 Series 4K Roku TV

The Fire TV Omni is the pick for a big-screen living room: 65 inches, hands-free Alexa built into the set, and four HDMI ports. The Pioneer R851 is the pick for a smaller room or a second TV, where 43 inches fits and Roku's interface is the draw. Both are 60 Hz LED sets with HDR and four HDMI ports, so the real split is size and platform, not picture technology. Owners of Fire TV sets praise the voice control and criticize ads on the home screen; Roku TVs are liked for a simple, neutral interface, and Pioneer's budget sets get mixed marks on brightness and sound.

• Choose the Fire TV Omni if you want the largest screen for a main room and prefer Alexa voice control without a remote.
• Choose the Pioneer R851 if you need a smaller set for a bedroom or kitchen and prefer Roku's plain, platform-neutral home screen.
