Putting aesthetics aside, iOS has a better app ecosystem and part of that is driven by Apple hardware (including having fewer devices to support) and software advantages. For example, I’ve read that the iOS audio stack has lower latency.
If you like GarageBand, then you aren’t going to want to go back to Androi because there’s nothing as good.
The integration with Apple desktop computers is pretty compelling as well. It’s part of the reason I wish Microsoft would buy Android from Google. I think they would do something similar for the rest of us.
