Apple I phone 5s is best phone ever in comparison with 6 and even 7series. I got my phone on jan 2014. and I am using it till now. I used sony, htc and blackberry but it is ultimate. Free from hanging, fast and good features. only drawback is its battery life. it really sucks. If you are using 3g or 4G network and cellular data is on, battery will drawn in 6 hrs.
It is a tough phone too. it was fallen from 1st floor two times but nothing happened to it, only some scratches.
