I owned the Note 3. I was really fond of that phone. I went caseless and it was great. Sure, GPS sucked (Ingress), and it had WiFi problems... but I liked it. Note 4 didn't interest me so I went back to iPhone (6+) and was happy. Coworkers with the Note 4 aren't happy with it, even considering going to iPhone even though they are heavy Android fans.
The S7 Edge is interesting. I've held it. I've used it. The camera is nice. Don't think I'd trade it, with Verizon's adware, for my iPhone 6s+. Note 7? Hmm. If S7 is any indication with Verizon...
Recently held and used a OnePlus 3 and was very impressed. Android has come a long way but adware is still probably my biggest quirk (Verizon). I don't think I'd give up AppleCare+ and ability to text/call from my Macbook.
Sorry for the ... long winded post - leading up to a direct reply to the OP: Yeah, the 7 didn't interest me when I had my 6+, so 3 months ago, sold my 6+ to get the 6s+ to hop on the Apple Upgrade Program because I wasn't going to wait for the 7. 2GB of ram, faster touch id, and 12mp camera was worth it. I'm happy with my 6s+ and won't be stressing the 7 at all. Next year? I'll be looking to upgrade, tho probably with Apple. May even wait another year to get most value for my $.
