I need to use Chicago style. Which of the three versions that come with Zotero should I use?

Zotero ships with three variants of the Chicago style (formatted examples of each style are shown below). The author-date format is most popular in the physical, natural, and social sciences, whereas researchers in literary, historical, and artistic fields mostly use note-based styles. For the note-based variants, the notes can either be self-explanatory and come with or without a bibliography (full note), or serve as a reference to a bibliographic entry (note).
