I also have tried it and seen
Kodi running on firestick and Apple tv and also on several different devices and honestly the apple tv version is better than almost all of the others. It’s super responsive where most of the android boxes kind of lag, save maybe then Nvidia Shield but I feel it’s even faster than that. Running Seren on it the content plays almost instantaneously. It’s click, pause, video starts, even 4K titles.
