The service? The Hardware? The App on the hardware? (Great job naming Apple...)
I agree that the Apple TV is the best experience one can have. It can be further enhanced by using a single app (Plex/Plezy/Jellyfin/Infuse/etc). Jumping between streaming services and their hostile, horrible UIs is such a pain. The Apple TV app was meant to improve that situation but without buy-in from all the streaming providers (which they will never get) it's always going to be playing second fiddle to the high seas.
