Samsung has the great screen, tons of RAM to run whatever you want, all of the great features. It also has touch wiz, so enjoy that.
The only Android I consider using anymore comes from Google. iPhone just works, though. I went back and forth for years literally. I think I may not go back to Android this time. It's been six months now with my 6s+.
I get bored with my iPhone after a while so thats why I have both the Galaxy S7 Edge and the iPhone 7 Plus but it doesn't take long with the Galaxy to remind myself why I like the iPhone so much. Another example if I don't start Apple Music on the Galaxy in my car before I start rolling down the street the only way to get it to play is to pick up the phone and launch the app, then go to my playlist and select it, hopefully I can get all that done while at a light. iPhone I just press the button in my car and say play playlist mikes favorites and it plays (Mike thats me! (Don't tell anyone)).
