When apple first made the larger Plus phone back I thnk in 2004 or 2005, the appeal was about screen sizw battery life, and to a small extent, the camera. Really, all the larger 5.5-inch model had that the standard but this year, the iphone 7 finally gets OIS great for smoothing out shaky-handed pics and videos, and most importand think is iphone have two rear cameras one wide angle one telephoto, that can zoom in at 2x or even further digitally. And it can creat depth of field blur effect and better battery life, but not by a huge amount larger 5.5-inch display, 3GB of ram instead of 2GB its heavier and bigger and ofcoure it costs more.
