I think it'll depend more on how long you can keep the mantids, they require a decent amount of food and a separated space from each other (a pain considering an egg case can hatch upwards of 200 mantids!). I dont personally feed my cham any, but I would guess that the mantis (being predatory) has a higher phos content than other insects.
plenty of people here do use them, so they'll ring in soon enough
