Do you like the meat? Different than farm raised?
Depends on the age and sex of the hog. The males have perineal glands which if not removed correctly (and immediately), absolutely taints the meat with a "gag-reflex kicks in" odor. There are more glands along the spine and around the neck which have to go.
Mostly we shoot them because they're so destructive. A pork shoulder which doesn't stink like [disgusting metaphor which would get this post deleted] costs a couple bucks a pound. If shot clean and quiet (so the animal isn't panicked), and then processed correctly, most of the meat is OK.
This is one of the few invasives we can't blame on the British, cargo ships or tourists. The original Polynesian settlers brought wild pigs as a food source. We'll never eradicate them. But we can get their numbers down to the point locally where they aren't a destructive porcine army.
