Honestly, at this point, the only reason to go with either ecosystem is that Android, for now, allows you to escape Google, to some degree depending on how much work you’re willing to put in. IOS/apple doesn’t allow that

But, ignoring that, apple got there first. That’s what it amounts to. The first real smart phone was by Apple, and that gave them a leg up
