A more useful comparison of how the specs compare on saurfang would be something like. As you can see unholy has a mean dps of 17830 with a standard deviation of 434.55 and blood has a mean dps of 16162 and a standard deviation of 874.28.
Unholy generally performs better but the performance of blood randomly varies by a wider margin, that's all there is to it. Blood can do more dps but usually won't.
