Double Vanille. Tonka Imperiale is a bit too powdery for my liking. I love that the Double Vanille has cedar and a few other notes to break up the vanilla. I just get straight Tonka Bean from Tonka Imperiale.
A difficult choice! I think they are fairly similar. SDV has a boozy vibe (reminds me of my mother's bourbon balls), while TI has a more herbal tone under the vanilla. I would go for the SDV but maybe that's just me.
Double Vanille. Call me strange, but I seriously think the note pyramid is shaped like a donut. It might have to do with how smooth it smells, but I find it very hollow smelling, yet there's this outer richness to it.
The Tonka is very heavy, almost annoyingly sweet to my nose.
