You are right in that they both have their uses so calling it "superseded" was inaccurate. They are both available in the API. If you truly want to customise the entire delegate, including the branch indicators and selection color / behavior, QItemDelegate is what you want. On the other hand if you primarily want to respect the native look and feel or a style sheet, you should try to use QStyledItemDelegate. It gives you less control but generally looks more native. The main difference is that you then only get to control the text or icon layout and/or the editor widget. In this particular case it sounds like this is what the user needs.
