I've tried once to use hissers as feeders for monitors - being fed well and heated well (27...30C), both Gromphadorrhina hybr. and Elliptorhina chopardi breed like flies, newborns are uncountable. But they're too rough and spiny - and very readily using these roughness and spines for self-defense.
So - dubia, if you need large roach. Or archimandrita, if it's possible to keep really large colony, they're by far not the fastest-growing roaches.
I definitely prefer crickets, locusts, caterpillars, beetle larvae for reptiles...
For some ants - yea, they're quite good, especially for specialized scavengers like large Carebaras, they clean them from inside.
For others, opportunist hunters like Camponotus - they're too rough, even small nymphs.
