I switched back to Apple because of the poor geolocation support for navigation, and also the language support for Chinese, Japanese is horrible. Also more emojis. Speaking from experience with GrapheneOS. I would never use a non Graphene OS android. I prefer Apple over Google.

I have no issues on Graphene with geo support and don't need chinese, agree it is clearly not as polished as iOS Non-Graphene Android is also out of the question for me.
