I've not tested some of the more feminine Exclusifs on my skin (and others I've only tested once or twice) but I can speak to the quality of Coromandel, Cuir de Russie and my favourite Sycomore.
Cuir de Russie has a rather feminine vibe that keeps it from being a purchase for me, but I'd love to sample the parfum of it, as I think the leather would be richer and deeper than in the EDT. I like rich and strong leather notes.
The other two, however, are excellent.
I've never smelled anything like Coromandel (I wrote here earlier that I wouldn't compare it to LIDGE), it is strong and long-lasting, but at the same time I feel I could wear it just about anywhere and not feel out of place.
Although I understand the similarities between Sycomore and Encre Noire, the quality of the Chanel is so high that I view them as vastly different fragrances. Where EN is harsh, astringent and very autumnal, Sycomore is rich, smooth and much more versatile.
I still think the Dior Prive line is better as a whole, but that is due, at least in part, to the fact that Dior's whole range is unisex/masculine, where Chanel's is more unisex/feminine. I own both Sycomore and Leather Oud, and if I could only keep one, it'd be Sycomore in a very simple decision.
