From Note 7, I have gone to Pixel and my husband remains undecided between an Edge or staying with his 6S Plus. A friend remains undecided.
iPhone is not an option for either my husband or our friend because AT&T says they can't replace their Note 7's with iPhone 7 Pluses until last week of December or possibly not until the new year.
~~TL,DR part:
I could have gone with an iPhone 7 and very nearly did. But I use the headphone jack enough that its removal is a significant annoyance. I also want a phone that records stereo audio for videos, which Samsung flagship phones do, and a Google rep told me Pixel does, but iPhone does not. If I regret the Pixel choice, I still have my SE which is more than sufficient for most of my needs. The Note 7 was a fun media consumption device and photo and video recorder and pocket computer.
What I would miss most in parting with the Note 7 is the Samsung camera. Next would be the display, and finally, the irreplaceable S Pen functionality. Oh and of course the sound quality for my videos. iPhone records in monoaural sound which sounds flat compared to the richer stereo sound of a Note7 recording. I did not go back with Samsung because my S7 loaner had run very hot and was clearly defective in that respect. I don't like defects that burn my skin.
We can say that Samsung was a shameless copier and they were, but with the recent Galaxy phones they did surpass Apple in many respects. But to say they have QC issues is an understatement.
Sadly, looking around at issues that plague the iPhone 7 release, Apple seems to be having a wonky 2016, as well, in that respect. Hopefully Apple's QC issues remain confined to problems that do not risk consumer safety. Fortunately, the phones that are free of defects are indeed very nice. Let's hope the Plus returns to wide availability soon.
