For precise infos on the meaning and expansion of these variables, see
http://www.postfix.org/pipe.8.html
it really depends on your LDA and on what you want to achieve, but in
general, I'd say the order of pref is:
1- ${user}@${domain} (but this is only available for postfix >= 2.5)
2- ${user}@${nexthop}
3- ${recipient}
to see why, think about delivering an address with an extension:
joe+extensi...@example.com (assuming recipient_delimiter = +).
you generally want mail for this address to be delivered to the mailbox
of j...@example.com (possibly in a "extension1" folder).
of course, if your LDA can "parse" addresses, then this handling may be
delegated to the LDA. but since postfix functionality comes for free...
