I wouldn't consider either Chergui or Serge Noir to be orientals, and I'd best most basenoters would agree.
Chergui smells miles better than Serge Noir to my nose. I'm not disgusted by Serge Noir (it's not in the same league as Musc Kublai Khan), but don't much care for it.
I think all of Pluran's suggestions in the post above mine are worth a sniff. That's a good selection.
