Hello Dear friend, AOS vs IOS, it has similarities on the apps performance, but AOS has more freedom, than IOS, IOS call it security but i called BS, they want to control money flow thats the reason why you need to buyit almost everything on IOS unless you do a Hard or Soft JailBreak. AOS is just simple like downloading from a built-in browser an apk extention file and then click and click and is done. now on hardware performance it will be based on device type and brand. tipically Samsung,LG,Google are leading market on perfomance. IOS is only stuck with one model so it suck.
