Below are pictures of both the 6 and 6s cases. Both are less than a week old. The phone shown in both cases is a 6 I took the pictures with the 6s. I actually like how the leather feels on the 6s case and it feels like it's a higher quality build. The 6 case very slightly "squeshes" in slightly on both the 6 and 6s while the 6s case does not on the 6s. They are both equal in terms of difficulty with putting on and taking off. The lip around the screen feels slightly taller on the 6s case. The 6s buttons are harder and I think overtime will provide a more "clicky" feel once broken in. IMO if you don't have either get the 6s case for the 6s and the 6 case for the 6.
