Semantical differences, methinks. My organic perspective has that mulch should both insulate the soil against the drying effect and feed the soil too - as the leaves and hay break down rapidly in a moist environment they form a humus layer that the nanners feed from. Critters have predators if predators are allowed and I've never personally had a problem. But for those that don't do organic, I can see where bark would be preferred.
Be well,

On the negative side, during sumer, slugs and snails will make their home in it.
Bark will decomposes, though slower, so it does add a bit to the nutrient and humus level of the soil. If that's your main concern, hay is indeed definitely better.
