Well, catfish, deer, wild pigs are all good to eat, but preparation, care of the meat, age of animal, and in the case of catfish, species and type of water are all relevant. I do my own butchering, and my family exists on wild game almost exclusively. I wouldn't prepare a meal from a full grown rutting buck the same way I'd prepare a meal from a 60 lb fawn. I wouldn't say one is better than the other, just require different approaches.
