Software wise, the IPhone will function better for longer. I always had a problem with my Android devices getting sluggish. I've noticed this among a lot of other Androids as well. Recently went to a concert where drones of people were snapping pics. Every droid I saw took several seconds to focus and snap a pic. Whereas the iPhones were just plugging away.
Used to be a Samsung/Droid fanatic. I went iPhone a couple years ago and haven't looked back. Although, Samsung pics always seemed a tad bit crisper looking. I haven't really taken a lot of pics with my 7+ yet, but, the depth feature is kinda neat.
This is my poor example(excuse the poor focus, I was drinking when I took this and it's just an example of the bokeh effect that it's capable of right out of the box). I'll have to play with this more in the future.
Here's the non-bokeh version.
