The biggest differentiator is price. An entry level Android phone is about $300 while an iPhone is in the $1000 range. And to be honest, anything more than an entry level Android is luxury these days. I say that because that's what I have and I have never felt held down, except maybe for pictures, but it is good enough for my (lack of) skills as a photographer.
So, Android may actually benefit from a lack of differentiation: like iOS, for a third of the price seems like a good value proposition.
