Bought the 6+ last year, kept it for a week and then exchanged for a normal 6 as thought was too large. This time went for a 6S+ and have kept it. Really pleased I went with the bigger screen device. Wouldn't go back to the normal non '+' size now. So next iPhone 7 WILL be the '+' again. Have no issues with its size in pockets etc.
I think it comes down to what you'll be using it for.
Had no interest in getting an iPhone but couldnt refuse that price.
