Which is better for a bright living room?

The Plus Series. Its Mini-LED backlight with full array local dimming pushes more brightness and holds contrast better in a bright room. The Select Series is direct-lit LED without local dimming.

Is the Plus Series worth $100 more?

Yes if you watch a lot of HDR content or care about sound. Dolby Vision, local dimming and Dolby Atmos are real upgrades. If you mainly watch cable and streaming in a dim room, the Select Series covers the basics for less.

Which has better sound?

The Plus Series. It has Dolby Atmos and a built-in subwoofer. The Select Series uses standard built-in stereo speakers, so a soundbar helps either set.

Do both run the same Roku interface?

Yes. Both use the Roku smart platform with the same home screen, app store and 500+ free channels. The Plus Series adds a hands-free Enhanced Voice Remote and a lost remote finder.

Which is better for gaming?

Neither is a gaming set. Both are 60Hz panels. The Plus Series adds four HDMI ports, which helps if you connect a console, a soundbar and a streamer at once.

Neither maker publishes a lifespan figure, and both carry the same Roku TV software support. Buy on picture and price rather than durability claims.
