Were I inclined to be purely objective, I would tell you that the ages-old Hue/Saturation command is growing somewhat long in the tooth. For example, if your primary purpose is to increase the saturation of an image, you’re better off exploiting the Vibrance command or the Lab mode.
Even so, Hue/Saturation continues to do something that no other feature does: It lets you edit one range of colors independently of all others—without defining a selection or mask—all from inside a single dialog box or palette.
