I own Imperial Millesime, and I`m waiting for a bottle of Epic. I love both. They are two completely different scents. The Imperial Millesime doesn`t last long, and you have to go for 6-8 sprays to get some projection. Epic on the other hand, is very strong and potent stuff. If you should wear it to work, only 1 spray is enough. Beyond that, two sprays is enough and you can easily detect it on your skin the next day even after a shower! This is high quality stuff! M-I is great during spring/summer and warm weather. It has a classy aura, and suits every occations. Epic is best without the sun. I would say autumn/winter. You can use it in summer also, but very sparingly. If you buy a 100ml bottle of Epic, it will last forever. It`s hard to decide between these two fragrances, but I think I would go for Epic if I must pick only one. Much because of the great sillage and longevity. It took me some time to like it, but after a while it "clicked", and now i Love it! Definitively the most masculine scent in my collection. Important: -Try before you buy!
