I've been using Apple TV for two seasons, after using a PC laptop.
ATV is much better. It's easier, quicker to start & quicker to update.
The remote is not good and can be frustrating to use, supposedly the newest version is better.
The limit of two BT channels isn't too bad, the companion app can be used for 3+, or if your trainer
has cadence, you only need the two (power/controllable/cadence on one channel, HR on the other).
If you use a PM, you may be able to use "Power Match" within you trainer's app (I can with my Kickr18),
so effectively my Assioma pedals are my power source & my Kickr is my controllable.
I double record with my Garmin 530 so that I get L/R balance & respiratory rate.
Zwift goes to Strava, the Garmin to GC.
