Mealworms, superworms, kingworms, and wax worms are all not optimal feeders. However, they're definitely very okay to add some to the diet as frequently as every few days, but not great as a staple.
The best worms are phoenix worms, butterworms, silkworms, and hornworms (never feed wild hornworms though, they are toxic due to the plants they eat, but are safe if raised on artificial diet).
You could use phoenix, butter, and silkworms as staples.
