Pinned hinges are still very common. I now use Robart pined hinges exclusively, but I have used my share of CA hinges. Most kits/ARFs come with CA hinges I believe mainly because they cost less (lowers kit/ARF cost) and they are easier to install. There is nothing wrong with CA hinges, but I believe the Robart hinges are superior, but they do take longer to set and cost more than CA hinges.
