I love both scents.
Tuscany is much more of a traditional fougere - the way that the citrus combines with the woods and aromatics to generate a real outdoors kind of feeling is pretty special.
Devin is a much greener fragrance. The galbanum in the top notes give it a torn-branch-cut-grass kind of bite, that combines with a bit of castoreum in the base to give it a hint of leather.
Please sample Devin. It is one of my favorite scents, and any fan of Aramis scents deserves the opportunity to enjoy it.
