I feel that the reformulations of both Dior Homme and Dior Homme Intense have been moved slightly away from the iris and more towards gourmand territory.
This has been my experience, after testing and comparing all three formulations of Dior Homme (vintage, first reformulation, and the current formulation). The vintage has slightly more iris and is lighter in the base notes, while the current formulation is a bit sturdier and more robust, with slightly toned down iris. That middle formulation is the only one that disappointed me -- it was a bit weak and watered-down. Bottom line: the current formulation (summer 2011 and later, silver collar and black stem) is very good and easily worth getting.
