Basically anything before the reformulation is great. The old juice was golden colored, the new juice is light green. I have a vintage edt that's probably from the 90's and the edc, which is maybe a bit older. Like rach said, the old stuff has a smoky component that's missing in the new stuff. That said, it was easy to get the vintage stuff fairly cheap for a long time, but I just went on to ebay and it looks like the price is creeping up.
