Stacks and Queues

Another non-obvious obvious thing (NOOS).  Stacks and queues are
"dual" as they represent two ways of traversing a tree: depth-first
and breadth-first.

Now, is a breadth-first search necessarily less efficient than a
depth-first search?  It seems it needs more bookkeeping information.
Or is this a consequence of how I usually implement?
