No doubt apple since decades has maintained its uniqueness in market, be in service provided or the product concepts.
after using iphone 6S for 6 months now, I will tell you whether android or IOS will suit u.
1) no doubt iphone has its own class and if you want to go by that, big yes, apple products give you best of quality and experience.
in case you are a app freak just like me, keep tonnes of music, games and all that crazy stuff, iphone is not for you, with just a limited space which you will soon run out unless you go for 64 gb or more model which costs a lot.
No doubt quality you get in iphone its incomparable but difference is not so large, say the mobile camera quality, you have so many other android phones with much better camera widget.
2) if you are brand savvy go for iphone but if and if ur techno savvy there are many better options available like nexus 5, do proper research before you buy any mobile depending on your need.
