It's hard to say without using it, but the gut feeling I get from 3D Touch is that it will be very useful. It strikes me as an innovation in the same category as the finger-no-stylus approach of the initial iPhone and, more recently, Touch ID. These features initially seem overhyped because they're such 'little' things, but because they affect your interaction with the device constantly, it'll be hard to live without once you're used to them.
