For me I've thought of it like this. My note 7 was stuttery out the gate but settled by week 2 and ran smooth from that point. However, the s7 edge has ran smoothly from day 1 and even a bit quicker. As I said before on other threads, it may be due to the Note 7 having several extra software features but still using the same hardware as the s7/ s7 edge. Nevertheless they both run great and that was just my experience with my two units. Also, some like Grace ui, I personally didn't, while it's more elegant, I found myself annoyed with how it handled quick settings and folders. It seemed counter intuitive having to swipe right to left once inside a folder since I'm use to swiping up and down. And quick settings menu seemed slower and functionality wasn't as easy as it's handled on the s7 edge IMO. I fear Samsung will bring grace ui to the nougat update this fall though.
Even though the note fits great in hand, I like the form and fit of the s7 edge just a smidgen better. I usually get notes with slim cases but with Samsung doing a great job packing a 5.5 inch screen into such a small body with the s7 edge I got a mophie 3400mah battery pack case and it fits in hand wonderfully despite the added heft and weight. Which also leads me to this, the s7 edge battery has been better then my note 7 (not counting the mophie case), only by maybe 20 min sot but hey it is what it is.
Also, the s7 edge screens gentler sloping edges makes edge swiping easier and more satisfying (especially with a case on), and by the way in this black color the phone looks great.
With all that said, I do miss that coral blue color on the note 7, iris scanner, day and night blue light filter, notifications on aod, and spen functions. However, is it worth paying restocking fees, taxes, activation fees, spending 6+ hrs setting up a new phone to my liking for the 4th time since August 19 (exactly 1 month to the day)? I'm not really sure.
