One thing I have to say for the 6s Plus is I loved using it caseless. On the other hand, even though I prefer the overall size of the 6s, I cannot handle it caseless. It's too little and slippery. The size and weight of the Plus stays in the hands much better. I can't use the 6s without a case. I felt the same about my 6. In contrast, I hated using anything but the slimmest of cases with the Plus. I would have used it naked if not for the fear of having no drop protection on it, and it definitely requires two hand at all times when it's caseless.
