There is no doubt that for the majority of people that use a Mac, an iPhone is the better choice. Syncing is given and you do not have to worry about anything. I would come back to iOS if it solves the issues that bother me (especially the folders and animations). When I use an iPhone I have the feeling that the OS is an afterthought! It was not designed for large screens. The back button of most apps is on the top left corner, as most UI elements. Yes, there are gestures, but they are not available everywhere. On Android the back button is located on the bottom left. Much easier to reach.
Another thing that I do not want to lose, are the soft buttons, especially the soft button that accesses the multitasking menu on Android. I always found it very cumbersome to double click on the home button to access multitasking on iOS.
Also, I do not understand the hype of 3D Touch, even if other OEMs will of course follow in 2016 with similar features. Having to press stronger and more deeper to access app options seems unnatural to me. Most of the times it is easier to just open an app and do whatever you want. Also, why have 3D Touch? Why not just press a little bit longer to access similar menus? I forgot, it is because Apple is using this to rearrange home screen icons. On Android I see no need for 3D Touch at all.
3D Touch is unintuitive and strange to use, as many other things that Apple has brought on the market the last 18 months. I am beginning to believe that now we see Apple without Steve Jobs. His influence is nowhere to see anymore..
