My wife had the 6. Now she has the 6s. I had the 6+ and now I have the 6s+.
So, both phones are in the home and used daily. I've handled my wife's 6/6s and she's handled my 6+/6s+. She still considers the 6+/6s+ to be too large and I get the "phablet" comment frequently.
I love it. But my wife is no convert. 😉
