  I'm a EDP fanatic so I could go on and on about 
  the EDP features vs. Jamman features, but instead I'll take another approach 
  and avoid religious discussions.
   
  Get an EDP because you can probably order one 
  with a 30-day return policy.  If you get a Jamman, you'll probably have 
  to buy it from an individual who is unlikely to offer a return policy.  
  So if you don't like the EDP, you can return it.  If you don't like the 
  Jamman, you'd have to re-sell it to recoup your bucks.
