THIS!
I couldn't care less about a giant phone. I'd be much happier with my same old 4" phone. I guess I can live with 4.7" but its extremely irritating that they are turning the huge phone into the flagship model. It should be the same, perhaps with the smaller phone having a slightly higher DPI because it has the same resolution in a smaller package. Instead the 5.5" is going to have OIS, better resolution, better DPI, and have a sapphire cover. They've managed to sell hundreds of millions of iPhones with small screens, I think its safe to assume we don't all want to hold iPad minis to our heads.
