It's mostly a mechanical thing, dealing with ease of construction. I'm sure there's some electrical differences but probably inconsequential in most cases.

Doc is correct. On the parasitic elements it makes no difference. The driven element may or may not need to be insulated depending on the type of matching device you're using.
