The 7 series and the 5 series are the ones that set the pace for future iPhone, as far as asthetics and design. The 7 to me was revolutionary so to speak cause Apple went outside of their comfort zone with design and it was great! I had the black one, jet black. I then got the 7 plus in the Red Color the day it was released on my lunch break LoL. That red color is amazing every time, so bold and for a good cause.
