There are people who love using iPhone and some just like Galaxies. Talking about my experience then I have used both of these folks. And I would say that if you are kind of a person who likes to customize mobile then I would recommend Galaxies and andriod but if you want to keep it simple and sweet then Ios and Iphones are the best option.
IPhone sort of restricts you with Apple only whereas Galaxies and andriod keeps it with you in a natural and effective way.
Reason why I prefer Galaxies over Iphones is that Iphones cost more than Galaxies and other Andriod handsets available right now in market. So guys what are you waiting for choice is yours make it big and large .
Last thing to say that Iphone give a premium and solid feel in hand and even Galaxies too but keep one thing in mind that if they hit the surface they both screw up on heavy damage. Thank you.
