Do honeybees carrying pollen "hit" the tiny stigmas in each flower as often and as thoroughly as tiny, solitary bees?
This probably depends on whether the flowers are self-compatible. If so, then any visitor that moves around on the flower is likely to pollinate. If not, then honeybees, by virtue of grooming pollen into the corbicula, are probably less likely (on average) to have free grains of pollen un-groomed that can carry over from one plant to another. The entire ventral surface of a typical halictid or andrenid carries pollen - LOTS of it - which must certainly increase the probability of cross-fertilization.
