My honest opinion is that the S7E is a great phone, but I am underwhelmed...
There is a fatal flaw in the Note 4 that forced my upgrade, so I went with the "latest and greatest". However, the S7E has a smaller screen (2/10th's + what you "lose" on the edge), the camera, while adding many features, is only 12mp compared to 16 (very noticeable when you're editing). Neither the Edge nor the Stylus added any significant feature to the phone, but the stylus never got in my way whereas I often find myself inadvertently touching an edge because....well heck, it's hard to hold the phone without touching an edge. The phone does appear to be really well built, but the design itself makes a protective case impossible to build. Traditionally speaking, a raised lip on the hardcase would prevent your flat-screen from actually contacting the "sidewalk". You can't do that with the S7E without covering the edges....
Still a great phone, but not an upgrade from where I came, and I use the edge about as often as I used the Stylus....
