This is my understanding as well. In a classic MC problem, global illumination with path tracing, low discrepancy-based sampling converges about twice as fast as random numbers. The Cycles renderer in Blender doesn't even give you the option to use random numbers, just a choice of low discrepancy sequnces [1].
