When to choose a Structure over a Channel? Structures look interesting because you can reorder entries manually, generate breadcrumbs and visually see a hierarchy of entries. Besides this, what are the primary consideration when choosing a Structure over a Channel?
Ordering and Hierarchy are the main benefits but they create a couple of side benefits such as the ability to


get the "children" and "parents" of an entry
get siblings including next and previous siblings


The best part is there no real downside, they have all the features and functions of a regular channel PLUS the structure.
