Re: S7 Edge or Note 5?
S7 Edge. The loaner one I used was God awful silver/gold. I had a crappy case too and I always pulled up edge display not intentionally. Rarely did it without meaning too. Grace UX destroys touch wiz i loved using it and missed it when using the s7 edge. Lack of HDR video support, stylus, and retina scanner are the true N7 exclusives.
There will be more cases/screen protectors for the s7 edge since it's been longer. Unless every single s7 edge blows up Samsung will support it and it's already confirmed for nougat and grace ux. So aside from screen size, retina scanner, HDR video, and s pen the s7 edge isn't as different and will be better when it gets grace ux.
For those who got to keep all the fast chargers or invested in wireless charging pucks those will still work. Only true nitpick I have with it is 32 GB onboard storage and the edge display is implemented better on note 7
Truthfully the pixel xl is 5.5 which is around the s7 edge size. Although S7 would have less headache with screen protectors and glass ones too
