This one opens with, you guessed it, bubblegummy vanillic notes, supersweet and cloying, not to mention insanely chemical. It rapidly mellows into a sort of sweet woody/foody thing, the cardamom, before sticking a woody amber landing of mostly benzoin, cedar, patchouli, and vanilla. Rabanne attempted a sage or lavender note here, but it just smells of nakedly chemical sclarene. There's also a bit of a scratchy quality to the amber, suggesting garden variety amberwood/Ambroxan at play. Meh. You could go wild and buy a bottle of this, but only if you happened to love all things Rabanne and had a limitless budget.
As for the comparison to Baccarat Rouge 540, all I can say is I haven't really gotten into that one, and often wonder if Francis Kurkdjian single handedly ruined perfumery forever with it. In our post-Baccarat world, the landscape is awash with bubblegum-laced quasi-gourmand fragrances, and I'm really starting to hate the world because of it. If you want to smell like this, but prefer to smell interesting, wear Qaa'ed. If you desperately wish to cement your NPC status by losing all unique identifying traits and wandering with the herd repeating pointless memes on X, this is for you.
