Aside from grouping, iOS notifications are better for me.

It feels like you control the messages you get, how they're positioned, what priority they get etc; much more on iOS. I'm sure this is actually release dependent, I can only speak from the old CM and modern Samsung ROMs.. but iOS generally >feels< a lot nicer, like I'm in control; non-removal notifications, general frequency and lack of notification location control contribute to this.

Newer Android version do bring a lot of control, you can disallow applications to send specific types of notifications and set up how the notification will be made notifiable; vibration, tone, none at all, blink LED, etc.

You can set priorities too IIRC.
