I am planning to buy a new phone soon. What should I go for: Android or iPhone? Why?

it all depends, if you are already using android eco system (Android TV, Android Wear, Chrome book etc ) then go for android, if you are iOS type (Ipad, Apple TV, MAC , Apple Watch etc) then iPhone. You are neglect this all at all and go for what ever you like. As i said it depends on personal preference. 

because android and iphone is the most used phone worldwide. most application made are due to the demand of this phones

I choose android, because I am familiar with its tools and it is user-friendly

• iPhone: tons of limitations.
• Android: no limitation.Why would you want to pay more money for more limitations when you can pay less for no limitations?

Android) It is easy to use
