Never get a Samsung TV in any case: not supporting all TV standards properly, bad picture quality, unnatural colours (even calibration doesn't help much), slow (outdated) cpu inside causing slow GUI control, software support is laughable. Especially in my professional experience... do not use Samsung. Yes their devices are cheaper, but do not expect quality, rugged or functional "smart" software inside.
Personally, I'm waiting for other TV brands to revert to developing a simple TV with very good picture quality again that does not have any so called "smart" things inside. An AppleTV 4K is way better for al "smart" things. Even a RasberryPi is better than the crap that's inside most TV's.
I bought the current AppleTV 4K back in 2017 just as a gimmick. Back then I was very sceptical about IPTV and stuff. I had seen the older AppleTV 2, so I wasn't expecting much, but man... the AppleTV 4K amazed me. The Netflix app alone was way faster than the one on a "state of the art" test set topbox I got from the cable company. Within a month it replaced our cable box at home. My family loves it. With all the subscriptions we use, it is cheaper than cable.
And today, with all the newer services it still works faster and easier than the "smart" top notch TV's. It only requires a ethernet cable or good wifi (802.11ac).
If Apple releases a newer AppleTV, I probably buy one if the graphics performance is exponential bigger. if the device will be the same size and the remote gets a find-my-remote option.
