3D Touch is marginal. The only time I use it is to move the cursor when typing to make corrections. Since I have a jailbroken phone, the tweak I have - running your finger across the keys - accomplishes the same thing and is easier to do because you don't have to press down of the glass to initiate the 3dtouch. So essentially, I don't use 3dtouch. Go to a Apple Store and try it out.
