Yes, PNG excells in muck diving. For those of you who are not aware of "muck", it is diving on bottoms not featuring major hard coral formations. Sometimes the bottom seems to be just plain sand.

AH! But look closer. You will often find critters you will see nowhere else. From all forms of frogfish and seahorses/pipefish, to the wonderful saddleback anemone fish (sometimes called the Panda).

If given a choise of reef or muck, I think I would have to go with the muck.
