I think phoenix worms are the best feeder period. Even when our beardie, Draper, doesn't want to eat for whatever reason, he will eat phoenix worms. Our vet told us to stay away from crickets, and use dubia instead. He said he see's way too many cases of reptiles getting parasites from crickets, and it's much less common in roaches.
Keeping feeders at our house has been 1000% easier with the phoenix worms and dubia. No noise, less smell, no escapes, easier to feed and breed (dubia), dont have to dust the worms, less chance of parasites.
+1 to silks and hornworms. For me, they are harder to keep, and are more expensive. VERY high on the nutritional value!
