I have always suspected that the reason that camera manufacturers include the 18-55mm lens as a kit lens is that it is the easiest range to produce decent quality images. You don't get the tricky compositions of an ultra-wide angle nor the technically more challenging longer focal lengths.
I don't do macro work myself as I have no interest in the genre. You likely won't see a lot of comments from me as I don't feel qualified to give more than some very minimal compositional comments.
