Which phone to buy? IPhone 5 or any other phone?

Hi I'm Harsha from India, I'm apple fan boy for so many years I got apple iPod, iPad now I want to buy a new phone I'm stuck up with which phone to buy? Either go with my natural love towards iPhone or any other phone? Even though I love apple somewhere in my mind its saying if I bring iPhone its gonna be same iOS, same icons, similar features, everything will be the same as I used in iPod and iPad, I'm feeling like wanting some change in my phone. But I still love iOS. Which one to buy? Apple iPhone or similar phone in htc or Samsung?

I had an iPhone 5 it's basic and easy to use but a week later I traded it for a note 2 because android in my opinion is far more superior than iOS. IOS 7 looks amazing but I like the android 5.0 key lime pie better but it's to each it's own. I would buy an s4 in this situation because of expandable memory and much faster and fluid. The iPhone has no gorilla glass to therefore dropping it can cause the phone to shatter completely. S4 has gorilla glass and it's much more sturdy plus it's amazing camera is a great addition to the smartphone.

Since your already heavily invested in iOS it's probably best to stay there. Because you will have to re-buy everything you bought if you switch. And iOS 7 is supposed to have changed the OS a lot so just go with the iPhone 5. Also Watch the keynote of iOS 7 on Apples website to help make your decision.
