I think it's great that you want to give credit to the entire group that did the comic. Is this for your personal collection or something you are creating for a more public venue? If a personal collection, I think whatever makes it easiest to find your comic. For a more public venue, limited to one author, then I would go with the creator as that would be the most likely, though not only, search word that someone would use. You, as a comic book reader, would probably have a better bead on that. I would search by series personally, as I don't know the authors of any comic books.

The goal of a library isn't about recognition of an author as it is ease of finding the materials. Recognition would be in the pages themselves. (paraphrased from a Library 101 class).
