I like the swiping motions to do everything instead of having to press the home button.
Sometimes you click too many times Wallet comes up or you hold too long Siri comes on. I don't have to worry about that anymore.
I have a regular iPhone 7 and an iPhone 7 Plus. Do like the screen feels as big as the Plus, but the body of the phone is the size of the regular iPhone. Much less awkward making calls.
Gestures for sure. The gestures are so much more natural than that dumb old fashioned home button!!
