Oriental is my favorite fragrance category but my current holy grail isn't an oriental. I think this is because I haven't tried enough orientals, so when I finally get my hands on something like PdN New York or SL Cherugi then they might claim the title of HG.
For now it's Azzaro pour Homme. Reasons: Smells amazing, year round use, great longevity and sillage, masculine and classic, readily available, cheap.
It's probably been through several reformulations but I have the current one and have no complaints. This means it gains points as I know I don't need to look for vintage.
