I don't have a Note Pro to compare but I know the 6s will have a much better camera. Mobile cameras are advancing quickly, and even the Note 3 had a better camera than the Note Pro.
IPhone 6s is a 12MP camera compared to the 8MP in the Note Pro. It will capture more detail, and it is much more capable in low light than your Note Pro. IPhone 6s plus would also have optical image stabilization for smoother video recording.
