Damascus will be as good as the steels (and metals) used to make it; the steels, and of course the ability of the person that made the damascus. The proper heat must have been used in the making of the damascus. If not there is a chance that some of the layers may end up not getting properly welded. This can cause lot's of problems in a blade including the possibility that pieces will flake off when the blade is being sharpened, and structural weakening. Also, just like any other steel, heat treat is critical in determining the final quality of the damascus blade.
Now , off on a different tangent; Personally, I feel that damascus does not offer value on a user knife. In my opinion, the fact that it is way more expensive than the high end non-stainless carbon steels such as 52100, 5160, 1084, 1095 and O1, that it is no better than, leads me to feel that damascus is used to enhance the appearance of a knife and nothing more. If it can not outperform these other steels, and it costs substantially more, then its only added value is in appearance, not utility.
That being said, I love damascus. It doesn't matter if it is wootz or pattern welded, I think that damascus is worth the premium that you have to pay for it. The reason for my love of damascus; it looks so darn good. Not all patterns appeal to me; some look so downright gaudy to me that I can not appreciate them at all, but give me a nice random, or twist, or Turkish pattern, and I think they add immeasurably to the desirability of a collectable knife.
