The two I bought seem to be just fine.
I can't suggest replacing either an iPhone 6 or 6 Plus with these new models simply because theirs no compelling reason.
If Pink is your color then that's a reason. Beyond that the other differences are nice but not must haves as I see it.
One that I bought was the Pink for my wife. The space grey replaced my son's 5S.
My 6 Plus is doing well, so I will pass since Apple has failed to make the 6S Plus a compelling phone that I would feel is a must have worthwhile upgrade.
