The EF-S 17–85mm is a step up in build quality and in focal range compared to the EF-S 18–55mm lens. Its image quality is higher than the original and the Mark II versions of the 18–55mm lens. It is slower and has lower image and build quality compared to the EF-S 17–55mm lens, although it is cheaper and has a longer focal range. The closest lens to the 17–85mm in the standard EF lens range is the EF 28–135mm lens, which has the equivalent range on a full-frame sensor, similar image quality and image stabilization.
