Enjoying the swapping - great! It's very satisfying that an unloved bottle finds someone who appreciates it!
I have a sample of Virgin Island Water somewhere but haven't tried it (I get a lot of samples from profumeria owners who know me) - but don't think I have Fragonard MrsSchadenfreude. Haven't sought them out because many traditional Grasse offerings don't appeal to me (have a friend who works in one of the houses there). I do have a small bottle of Habanita by Molinard: it's a slightly scary tobacco-vanilla seemingly shaped with a chainsaw (I like to think it's a lumberjack's vanilla). Interesting, but not easy to wear, at least not easy for me.
There are so many perfume houses today (and each year many more) that I really haven't explored everything. I've found so many that do perfumes in the style that I enjoy (favorites: Chanel, Dior, Guerlain, Caron, Frederic Malle, Hermes, Lutens, L'Artisan, Comme des Garcons, Heeley, Maitre Parfumeur et Gantier, Histoires de Parfums, Nicolai, Tauer, The Different Company, Tom Ford, YS Uzac), plus I occasionally explore conceptual new things like perfumes by Geza Schoen, Odin New York, Humiecki & Graef, or Olfactive Studio. But there are also many perfume houses that do things that may be very good, but are not really interesting enough from my personal perspective.
Tastes in perfume are very personal: I know many perfumistas who love and collect things I don't get (say, light fruity perfumes or white flower bouquets or classic chypres); they usually don't like my favorites. (I even have a friend to whom I routinely send things I don't like - she usually loves them. And vice versa.) I've found most of the perfumes I really love by listening to men who collect perfume - I wear a lot of classic masculines and feel that they fit like a glove.
Today I'm going retro and wearing vintage Fidji. It opens with very tart, puckering bitter-green galbanum - I'm waiting to see what comes after. Not an easy perfume to love, and could not see this selling in Sephora these days - the opening is blasts of soap and bitterness. But there is an airiness to the heart that I like. Old perfumes rarely reveal themselves at the opening - they are usually very forbidding at start.
Wiggly one more recommendation for you: Cuir de Russie by Chanel has both birch tar and leather. I love to wear it in winter.
