i recently got an apple tv4. the interface on that is the best ever i have used
It makes any TV Smart interface look so antiquated and frankly rubbish imho
The remote is so easy to use and it connects up to my ecosystem
you simply do not have to put up with the smart interface that comes with the tv
Get a better little box, does not have to be Apple. Could be Amazon, Roku, Chromcast
That is why when i do get my next TV, i will not base my choice on the poor smart tv system, which they can not get right and change every five minutes
The reason i say the above is that i do not watch live tv
its all VOD for me and BLU RAY
