Anandtech Nailed the Note 7 review , I like this website: very technical and comprehensive.

Any S7 Edge owner is a waste of money to upgrade to the Note 7 , the Iris scanner seem to be not very reliable (but a plus for Samsung innovation sure) , the battery life comes in short to the S7 Edge (relatively lower battery capacity of the Note 7 , -100 mAh) , performance comes in par (same ship in both Sanpdragon and Exynos).
Note 7 Advantages:
1st HDR Screen in the mobiles market
Corning Gorilla Glass 5 instead of 4
Comes 64GB Internal (Default) with Expansion.
