I had a 5S when it launched until the 6 came out. I got the 6 at launch and used it until the Galaxy S6 Edge came out. The S6 Edge was cool to play with for a while, but the phone has big memory problems (Android 5.0.2 bug... supposedly fixed in 5.1.1)... like always have 85%-93% of the 3GB RAM being used even with all recent apps closed and running the built in "RAM cleaner." I missed the silky smoothness of iPhone, but I already sold my iPhone 6, so I had 5S in my closet (had a warrantied replacement that I never even powered on or used). Wow... this phone still hangs tough with performance and that form factor. I hope Apple considers making 4" versions of new iPhones in the future. I had forgotten how great the one handed use really is. I think I will use my iPhone 5S as my main phone for a while and keep the S6 Edge as a mini-Android tablet to keep around when I have a need to use something Android only (there are a few Android apps that I love that surprisingly have never come to iOS... like PicSay.... etc). I will probably root it to something custom and less bloated.... based on 5.1.1.
