Black Uruks were not the same sort of creation as Saruman's Uruk-hai. The Black Uruks were the result of selective breeding among orcs, while the Uruk-hai had the advantage of Mannish blood (most likely Dunlending, though it's rather horrible to imagine how Saruman convinced them to breed with orcs). I admit that the strongest orcs of Sauron's forces may have been as strong as or stronger than a regular Uruk-hai, but they would most likely be a lot rarer.

Sauron's armies tended to depend on quantity rather than quality. "Down from the hills on either side of the Morannon poured Orcs innumerable...forces ten times and more than ten times their match would ring [the Gondorians and Rohirrim] in a sea of enemies." Or, "...it was seen that even fear by night had scarcely over-counted them. The plain was dark with their marching companies, and as far as eyes could strain the mirk there sprouted...all about the beleaguered city great camps of tents..." When Sauron needed the big guns, he often brought up Half-Trolls and Haradrim riding Mumakil from the south. Also in FOTR, "a huge orc chieftain...almost Man-high" proves that even the largest orcs were not even as large as a Man, perhaps about 5'6" Also, this article here http://tolkiengateway.net/wiki/Uruk-hai confirms or at least agrees with my viewpoints on the Uruk-hai, and no doubt found more sources in the books than I can remember off the top of my head.
