We are all different and some like the 5.1 screen for easy holding and some would like the 5.5 screen for its real-estate. I prefer the Galaxy S7, since I had the iPhone 6s with the 4.7 inch screen and thought it was just not big enough for my liking. The iPhone 6s plus was too big for me when I held it at the store. You may want to do same when you can.
