I've tested all three formulations of Dior Homme (the original "vintage" version, the first reformulation, and the current version). I own two bottles of the vintage and a big bottle of the current stuff. While it's true you'll notice a difference between the old and new if you pay close attention, the truth is, for any practical purposes, the current formulation is great and quite close to the original. What's the difference, then? The original has a (relatively) bigger blast of iris in the first half hour or so, and the overall scent in development is more subdued. The current version adds a bit more bergamot at the top, and amps up the leather/cacao/vetiver base, making the whole thing more robust and longer-lasting. But really, it's a subtle difference. No one should hesitate to grab the current version; it's good stuff.
