I have an LG C8 with an ATV4K. I have a Samsung 8000 series with ATV built in. I prefer the Apple TV to the ATV app baked into a TV's OS. It's not even close. If money were no object, I'd buy a second ATV4K to use on the Samsung, as the experience of the ATV4K is vastly superior to using the app on the Samsung. I really hope Apple doesn't decide to stop producing the ATV as a device any time soon.
