It's a fair question that I've pondered myself.

First and foremost, I prefer Apple to Google. Apple charges money for their products instead of offering free services to monetize you.

So I have Apple computers and also Apple phones for myself and my kids.

I have looked into Graphene and I would consider it if it was just for me.

However, I do use Apple to manage their screen time, what apps they use, etc and changing them all to Graphene is not something I want to do because they would hate it and Graphene is not setup to provide that kind of kid management services.

I already consider a win getting them to use Signal.
