Having both and using them over an extended period of time will give you the best comparison of the two. I surmise that eventually one will win out over the other and become your main device for day to day use, but the other will be available as a change-of-pace device for when the mood strikes you. I do it myself, but cross platform. Nokia Lumia 928 and a BlackBerry Q10.
