After having Android phones for a long while, I finally got persuaded into getting an iPhone 5S a while ago. I've had it since the end of 2013, and I can quite honestly say I'm regretting ever switching away from Android.
It's hard to explain to someone who hasn't experienced both platforms...but with iOS I feel like I'm constantly being held back from doing this that would be totally doable on an Android. While not exactly a 'poweruser' on Android, I'm definitely missing the customization and control that I apparently was taking for granted in my old phones.
Samsung galaxy s2 and I hate it, I love that's it's a big screen and all but there is too many problems with the phone like the phantom menu press for instance its really annoying it will never do it on wifi for some odd reason
