I really like the output of pfctl -sr from either the console or debug, run command from the web interface.
It shows me the all the rules, in the order they are added/evaluated, and all the different rules (floating, interface, interfacegroups, etc) are in one list. I find it easier to manually parse or walk but you need to be familiar with raw pf rules/configs.
That's my preference, others with more experience in the GUI or the XML config may find a different way better.
