The reason for Android's Notification system being better than iOS, is solely due to the ability to turn off individual aspects of an application's notifications.
Google, the poor multi-billion dollar scrappy startup that maintains Android, made a payment app that has one notification setting, "Google Pay". So all the ads, promotions, everything.
3rd party apps like PhonePe & Paytm have a better system.
Android notifications are definitely nice. I just hope they eventually get the focus functions from iOS. I know Samsung already has it but still would be nice to have a built-in version
