Which is better for movies?

The VIZIO, because Dolby Vision and HDR10+ adapt scene by scene on more streaming titles. The Roku handles only HDR10, so Dolby Vision shows fall back to a basic HDR picture.

Which is better for gaming?

The VIZIO lists a gaming menu, Auto Low Latency Mode and up to 120fps at 1080p. The Roku lists a 60 Hz panel with no high-frame-rate mode, so both are 60fps at 4K.

Is the Roku worth $71.99 more?

Only if you value Roku OS, the voice remote and the fourth HDMI port. The VIZIO gives you more HDR formats and WiFi 6 for less money.

Which has more HDMI ports?

The Roku has 4; the VIZIO has 3. That extra port matters if you run a console, soundbar and two streaming devices.

Which do owners rate higher?

The Roku, at 4.8 out of 5 from 1,841 ratings, against 4.3 out of 5 from 13,044 ratings for the VIZIO.

Do both support voice assistants?

Yes. Both work with Google Assistant and Amazon Alexa; the VIZIO adds Apple Home and the Roku adds Siri.
