I adore
Susannah (
Susanna) but find
Suzanne to be somewhat dated although it's not bad.
Susan really bores me -- very dated.
Suzette is ok (my dh's cousin).
Susie is adorable but
Sue is just too "down home" for my tastes.
Sukie is ok. My fave nn for
Susanna is
Suzu or Zuzu (not that I'd want to be called that outside my immediate family). ;-)
