...Susannah's all over the name boards nowadays, but Susan has a crisper sound which appeals to me more. Although Susan and Sue are dated, I love Suzy as a nickname, or even Sukie, an old Susan nickname. As long as you don't use Sue as a nickname, the dated-ness shouldn't be too bad; I know a million middle-aged Susans, and every one of them goes exclusively by Sue, never Susan. Susan on its own makes me think of a young girl in the 40s or 50s with her hair in a perky ponytail, a "bobby-soxer".
