Do they vary by company, or are they pretty standard across the board? There's a couple of guns I have my eye on for my eventual 1911 purchase, and the contrast of parkerized frame and slide with a shiny stainless barrel and bushing looks stunning. For example: (That one has an aluminum frame, but just used as an example, the one I'm looking at is a Loaded with a steel frame, if that makes any difference). Though i see galleries of pictures of these things, some look like they hold up quite well, some have a lot of marks on them. I'm not going to cry if it wears a little bit, but I don't want it to look beat to death either. And this gun would be a range gun, not ever holstered or carried (can't do that unfortunately). Though I do sometimes get sweaty hands. In your experience has parkerized stood the test of time?
