They are pretty similar, extreme is a more full bodied version. I personally like the original better, I find the anise and cocoa mixture works better when not amped up as much as it is in the extreme. Longevity and silage is not too noticeable for me personally. All that being said, if you can find a legit extreme bottle, you might want to go for it, they are becoming more and more hard to find in some areas.
