Both are good options. It depends up on your need and budget.
Only demerits of Android: It slows down in performance with many apps installed. Price drop is drastic in 2 years. U need to tweak settings in Android to have better performance.
Apple price does not drop much compared to android phones. Apple provides very limited options for users thats why its performance holds good for 2 years compared to android. i hate apple because there is no back button but love it because it does not slows down like android.
It is my personal experience using both flavor.
