I would say my most adored single note, straight out of the essential oil or absolute bottle is hands down ROSE. Especially rosa damascena. It is so incredibly uplifting and almost otherworldly in its beauty--spice, dried fruit, flower--rose has it all.
However, I do not seek out rose in perfumes per se. I find that the artificial rose reconstructions are not satisfying for the most part. One reason I love Chanel Coco so much is because it takes advantage of the "preserved rose" scent that I adore in rose absolute. Most others try to mimic the live rose, and they almost always fall short for me.
I'd say that my love of rose absolute makes me want to seek out other spicy, fermented fruit scents. So, Shisheido Feminite du Bois absolutely fills that need. Other boozy scents are also great, especially when combined with amber accord (not necessarily ambergris, but the vanilla, labdanum, benzoin type mixture). Parfum d'Empire Ambre Russe is very boozy with an amber accord drydown.
As much as I love sandalwood...well, it is not in the driver's seat, lol
