Recently new owner of AirPods Max and have been using them for voice chat, calls, music, gaming extensively.
I also happen to own a pretty good spectrum of other ANC headphones (QC15, QC25, Bose 700, MX3, Audeze Mobius).
In terms of being able to support all of those use cases for someone heavily invested in the Apple ecosystem... yeah, wow, they are fantastic. Quite honestly, they are not #1 for any of those use cases compared to that group - they do well in each, sure, but lead in none for me).
I'm going to keep at it for another week or so before I decide if I'll return them, right now I'm leaning towards no, which you may find odd, but here's how I've been thinking about it... I remember old iPhone reviews saying "the best camera is the one you have on you and use".
Honestly, none of those other headphones have been worn as much in a similar time period ever. I'm currently listening to more music, taking more calls on the same headphones, etc.
So at least for my use cases and devices (again, heavy apple: iMac, MacBook, iPhone, etc) they win the battle because they do well enough at everything and sit inside my device ecosystem (the ease of switching devices, etc) so well.
