It's a response size vs number of queries trade off.   What is
"better" depends on how the clients process the answers returned,
the contents of the answers and what you want to achieve.  There
are lots of variables to this and they change over time.

In the end it is a knob.  BIND 9.11 adds two more stops on the knob.
