Address Book Alternatives?

I know I'm not the only one who dislikes the skeuomorphic interfaces that Apple has adopted for iCal and Address Book in Lion. That tiny little shred of paper on the calendar and the "rich Corinthian leather" look of both apps drives me up a wall. I've switched from iCal to BusyCal and like the results so far, but I've yet to find anything that can replace the core functionality of Address Book. So I turn to you, the Internet, for answers.
