Which is better for gaming?

The TCL QM6K. Its 120 Hz native panel, game accelerator and four HDMI ports handle consoles far better than the Samsung's 60 Hz panel and three ports.

Is the TCL worth about $350 more?

Yes if you care about picture quality. Mini LED local dimming, Dolby Vision and a 120 Hz panel are the upgrades you pay for. If you just want a big screen cheap, the Samsung is enough.

Which has better sound?

The TCL. It has a 40 W ONKYO 2.1 system with a subwoofer and Dolby Atmos. The Samsung has 20 W 2.0 speakers, so a soundbar helps either way.

Which is better in a bright room?

The TCL. Its Mini LED backlight reaches higher brightness and holds up better against glare. The Samsung's standard LED panel looks flatter in daylight.

Neither maker publishes a lifespan figure. The Samsung brand is marketed as top-rated for durability and has far more ratings, but the TCL's build and 71.9 lb weight suggest a solid set. Buy from a store with a good return window.

Do both support voice assistants?

Yes. Both work with Google Assistant and Amazon Alexa. The TCL adds Siri and Apple HomeKit support.
