Which is better for movies?

The TCL 43S571G, because it supports Dolby Vision and Dolby Atmos, which the Samsung lacks. The Samsung still handles HDR10+ and HLG well.

Which is better for gaming?

The TCL, thanks to Game Accelerator 120 VRR for smoother motion. The Samsung offers Gaming Hub for cloud games but its 120 Hz mode is a DLG boost, not native.

Which has the better smart TV system?

They trade off. Tizen on the Samsung includes Samsung TV Plus free channels and works with Alexa and Google Assistant. Google TV on the TCL is clean and Google-centric but has no Alexa.

Neither maker publishes a lifespan figure, so there is no clear winner. Samsung markets itself as the TV brand rated #1 in durability, but that is a brand claim, not a tested comparison.

Is the TCL worth choosing over the Samsung?

Yes for most buyers, since Dolby Vision, Dolby Atmos and VRR cost nothing extra at this size. Pick the Samsung instead if free channels and Alexa matter more.

Do either support 120 Hz at 4K?

No. Both are 60 Hz panels. The Samsung's DLG mode and the TCL's Game Accelerator 120 are gaming features, not native 120 Hz 4K.
