According to the hogs age and size really. Generally I don't much care for a hog over 2.5 to 3 years or over 200 pounds in the wild. Really over 150 they start getting a little rough tasting. But in general, like whitetail, the females are the best tasting. As far as comparison to farm raised, the meat is a good bit leaner in MOST cases not all. It also has a deeper, richer flavor to it. Farm raised pork, in general is a very light flavored meat unless you didn't trim a lot of fat off. The fat is where the flavor is on them. It's partly why it is one of the best meats for smoking. It takes on flavors of additives much better than most any other meat. Wild hogs on the other hand, of course depending on their diet, has much more flavor to it.
