iPhone vs Android?

I've been wondering: Which is better, iPhone or Android?

Phone stereotypes

A new survey supports stereotypes that Android users are more likely to be late tech adopters who skew politically conservative, whereas iPhone/iOS users are more likely liberal, outgoing city-dwellers who make more money, take more vacations and enjoy the finer things in life.

This is described as a nonscientific survey. I agree with that.
