I have used both a lot, for a long time I was only Apple and wouldn’t touch Apple. Then spent some time with windows phone (the best of the mobile os but sadly Microsoft are...Microsoft and killed it) before trying android. I would not go back to iOS now. I see it’s advantages the key being it’s security and ease of updates, I don’t agree that iOS is simpler, it once was sure, not now, it’s also not more stable, it is frankly mental at times, iOS 12 may fix that.
For android through the live widgets, the launchers, native group email!, always on display, notification led, all of these things give me a device that I can actually use to do stuff, a device that doesn’t sit blank when I have notifications and happen to miss a vibrate or noise, but it has a few different ways to let me know. For me an iPhone is an expensive toy lacking key functionality to do stuff.
