I switched to the iPhone 6 from Samsung's Galaxy S6, but changed my mind after two weeks
The screen is simply stunning.
Calls are clearer.
Photos are look better

Android had something to do with it, but it wasn't everything.
One of the reasons why I slightly prefer Android is that it lets me customize the way my icons look and where I place them on my home screens. For example, I've placed all my icons towards the bottom of my home screen simply because I prefer having them there, and I've made all my icons white because I can and I think it looks good. Then there are the widgets like the minimal clock in the image below.
