To be honest, I haven't smelled any of your other favorite roses aside from Parure, the sale of which I still mourn. I didn't really think of that as a rose scent though in the way Rose Nacree or POAL are. I still love Iquitos and I'm happy I have a full bottle. I wear it all the time.
Portrait of a Lady is a really special scent, but it's so gigantic that I'd have a hard time wearing it very often. Rose Nacree du Desert is similar to PoaL but it's a bit more transparent and way more wearable. I'm not one to splurge on expensive bottles, but I may buy this one.
I just had an old friend ask me for advice for a fragrance for her husband. I made a few suggestions based on her critieria, but also said they should go to a place like MiN (they're in NYC) and sniff things. They ended up doing that and buying L'enfant Terrible from Joyvoy, which I've never heard of.
