Honestly IMO it doesn't really matter, but from a game design perspective it doesn't make sense to me that the rifle better for one tapping to have worse accuracy when going for a one tap. if the phantom is supposed to better for "spraying" (tracers, bigger mag etc.) then the rifle better for one tapping (always kills in head) then it should have better accuracy.

also cause itll make my friends shut up about how the vandal is "garbage and completely inaccurate"
