Why do you Prefer iOS over Android?

Hey, so recently my nexus 4 broke and I've been considering an iPhone. I've had a nexus s then a nexus 4, however I'm just not interested in android anymore. I like android a lot but no android phone appeals to me and I'm not excited about the new wave of android phones coming out. Im considering getting a 5s or a used 5 until fall so i can get a iPhone 6. If you have an iPhone and prefer it over android I would just like to know why and what makes iPhone better for you. Thanks for your responses.
