build quality?? Do elaborate?
What me and most people I know care about their phones is how quick it is, what it can do for then, and durability. I don't see how apple wins in any of those categories.
Apple wins hands down IME.
An Android (maybe only Samsung) might start as a fast phone, but with time, as apps get installed, more data stored on the phone, it starts becoming sluggish. I've seen nothing close to that experience on the iPhone.
Lightning port and plugs are a lot more durable than any micro USB that I have seen.
