I think it's a good set. Noir de Noir, as you know, is a chocolatey rose. Oud Wood was perhaps the first straightforward niche oud to appear in western perfumery, and is a good, realistic synth oud, with all the main notes firmly in place (wood, band-aid, animalic); it makes a good intro to oud. Bois Marocain, if I remember it correctly, is a rich sweetish woody (but I may be wrong here), and Arabian Wood didn't strike me as woody, more a rich floral, but I haven't smelled it carefully.
I more or less liked them all; I own oud wood, and I think I'd be happy with Noir de noir and bois marocain as well, though I am not planning to buy them soon. These tend to be more on the warmer, stronger side, so stereotypically they're for cooler weather, though I don't see anything wrong with wearing them in the summer. For Noir de Noir, you need to be comfortable wearing roses, as the rose is big.
