Centipedes or millipedes - which are the good guys?

Centipedes

In general, things that run are predators, chasing other creepy
crawlies. Things that are sluggish are prey, busy munching on plants.

But that said, most 'prey' aren't harmful, and do a sterling job of
clearing up rotting leaves and general detritus.
