It covers a wide 24mm to 127mm equivalent. This would be super for a walk around camera and would also match very well with a 70-xxx mm lens. The overlap of the 70-85mm length should result in less frequent lens switching if you are working with a single camera which most photographers do.
As far as the comparison between the 16-85mm and the 18-55mm lens (in focal range only - not considering any IQ differences), the 2mm difference on the wide side is quite a difference. I am still an old school guy and cut my teeth on full frame cameras, so I always think of lenses in relation to their equivalent focal length.
The wide side of the 15mm is a 24mm equivalent while 16mm is a 27mm equivalent. I owned a 28mm lens for my full frame manual focus film cameras and I occasionally borrowed a 24mm lens. There was an obvious difference on coverage between the two lenses.
However, the greatest advantage of either the 16-85mm Nikon or 15-85mm Canon over the 18-55mm lenses (of either Nikon or Canon) is on the long side! The approximate 127mm equivalent makes this lens quite handy for street shooting and for portraiture. I use the Canon 17-55mm f/2.8 IS lens as my go-to glass for all general and travel photography. It is however, really too short for walk around use (as a single lens) and just marginal for portraits but, I love the consant f/2.8 aperture and its super AF and IQ; so I stick with this lens. I solve the dilemma by shooting with a pair of cameras with 17-55mm f.2.8 IS and 70-200mm f/4L IS lenses. However, I would expect that this is not a solution which all photographers would opt for...
