Mulch splits into two jobs that look identical from the street. Bark, straw and wood chips break down, and that is the point of them: they feed the soil while they cover it, which is why a bed gets topped up every spring. Rubber does not break down at all, so it holds its depth for a decade and gives the ground nothing.
That decides where each one belongs. Anything growing wants the organic kind. A play surface or a permanent border wants the one that stays put. Buying on price alone gets it backwards, because the cheap option is the one you buy again every year.
