If you want to find out what the Creed scents smell like, you could always get some decants off of the 'bay.
Off of the top of my head, here are some clones in the wet-shaving world:
Creed Aventus: WSP Olympus, Fine Platinum, Stirling Executive Man, A&E Spartacus, Razorock Emperor, Captains Choice Venture (there are a few that I'm probably forgetting)
Creed Virgin Island Water: A&E St. Barts, Stirling Island Man
Creed Green Irish Tweed: Stirling Sharp Dressed Man, WSP Gaelic Tweed, Lisa's Irish Green Tweed, Wickham Soap Co. Shamrock Tweed (again, most likely missing quite a few)
Creed Original Santal: AOS Sandalwood, Fine Santal Absolut (not exact clones, but close enough)
Creed Silver Mountain Water: WSP Matterhorn, Stirling Mountain Man (there are more, but my mind is blanking)
Creed Royal Oud: Wholly Kaw King of Oud (it's close...maybe a bit more citrus)
