Of that list, I own Oud Wood and like it, although it isn't that oud prominent.
I think Oud Absolu is nice and have a small decant. Well blended and easy to wear.
Although I enjoy Dark Aoud, I wouldn't blind buy it as it can be rather polarising.
Current favourite "oud" scents are Epic Man (you could get that and it would cover all 3 threads - oud, incense and leather) and Songe d'un Bois d'Ete.
