Since ATT TV is offering free HBO/HBO Max for the 1st year, and a $100 rebate, I signed up for it today at the Entertainment level. I don’t have ATT’s little box yet, so some of the things I may say might change when it gets here. Equipment - AppleTV4K - app performance is very good. The guide is one of the nicest I’ve seen on any streaming app. And there are filters to help in guide management though a bit limited. Audio performance is worse than some streamers, mostly because the audio level is low but also because, even with their ‘premium’ product they couldn’t bother giving 5.1 audio! That sucks! DVR and recordings management is easy and the search function works very well. On Demand stuff seems very good though I’ve not played with it much. Seems to call another app for some of it and stay in the app for others. But the transition is smooth as silk. FireTV Cube - performance is totally unacceptable! Pig slow for all functions. I wouldn’t recommend using the FireTV for this at all. I’ll come back to this after the box comes in to report the good/bad/changed from apps on the AppleTV4K.
