I agree. I have the 6 plus. At first it was strange with how much bigger it was. Not that I am used to it, the 5 seems very small. The 6 plus has some new features and the camera is better than ever. I have kept all my iPhones in the Otter Box Defender series and have had no issues at all. When I traded in my 5, it looked like it was brand new except for the stratches of plugging it in to charge.
I don't know about the 6, but the 6 plus battery life is awesome compared to the earlier iPhones. I can play on my phone all day and don't need to plug it in to recharge.
