Shariffs products are excellent. One of the best sources of Ouds, Musks and Ambergris. He is a little over priced but he carries stuff that cannot be found easily. I have not smelled both of these but I do own his Dehn Black Musk which these two are based on. I would suspect that the attar is dilluted and the later has a higher quality Oud. I have sampled or own many of his products and if you have any questions please let me know and I owuld be happy to suggest something. If you really want a beautiful musk scent then try the Dehn Misk Maliki Supreme. I own this and use it sparingly cause it is fantastic. The AA Ajmmal Musk Ghazelle is very very similer to his Indian Red Musk.
