Acqua di Parma Magnolia Nobile is the only magnolia I've tried that I really liked, but it is fairly sweet and I think I've found that I love the smell of magnolias, but don't want to smell of magnolias myself.
Magnolia Romana by Eau d'Italie gets rave reviews and I'm dying to try it as it sounds more peppery and bitter green than sugary sweet.
I don't think Fracas has magnolia listed, but it can give off a magnolia/Southern decadence vibe.
Youth Dew Amber Nude lists magnolia in the top notes, but I don't find it. It is one of my favorites though and worth trying.
