It depends on where you want the note to be seen. Using the edit summary, it will be visible to only those who view activity logs and/or page history. Using the comment syntax, it will be visible to only those who edit without VisualEditor. A third option is to place some text at the top of the page. This would be displayed to anyone viewing the page.
