Which is better for movies?

The VIZIO, because it supports Dolby Vision and HDR10+, which most premium streaming titles use. The Roku handles only HDR10, so Dolby Vision content plays in a lesser format.

Which has the better smart interface?

The Roku. Roku OS is simpler and has broader app coverage. VIZIO OS works fine but leans harder on its own free channels.

Is the Roku worth $30 more?

Only if you value the Roku interface and its higher owner rating. On picture formats the VIZIO does more for less money at the listed prices.

Which is better for gaming?

Neither is a gaming TV. Both are 60 Hz panels, so a console is capped at 60 fps. Pick on price and inputs, and the VIZIO lists three HDMI ports.

Which is easier to wall mount?

The Roku is lighter at about 20.5 lb versus 21.14 lb, and its frameless design sits flush. The VIZIO supports 300 x 200 and 200 x 200 VESA brackets.

Do both have Bluetooth headphones?

Yes. The VIZIO lists Bluetooth headphone pairing and the Roku lists Bluetooth plus auto speech clarity for late-night viewing.
