It depends - what goals are you trying to achieve?
I can imaging different goals:
- speed of prototyping
- ease of debugging
Depending upon what you want I'd chose different methods.
Records are the most efficient, but need a bit of tender loving care
when you modify code. Maps are great if you don't really know what keys
you want and are doing exploratory programming.
Perhaps you should start with maps and change the representation to records
when you fully understand your problem.
