It's a huge upgrade from the 5S. You're viewing this from the wrong direction. This was never meant to be an upgrade from the 6S line. It's a hybrid of the 5S and 6S ... a phone with modern hardware in an older form factor that people do actually want because they prefer the size.

You're going down from a paltry 4.7" 750p screen to a 640p 4" screen - THE EXACT SAME DISPLAY AS THE 5S in 2013. didn't you catch the Apple presentation intro? It's all about RECYCLING AND REUSING! They did this on purpose to prepare you in case you dare use your brain to think hard about what Apple is really doing.
