For a pack string mules are the better animal (horse vs mules) no question. I'd rather lead 9 mules than 3 horses. Mostly they just fall in line and do their job. And for riding in the mtns hunting there isn't much wrong with them either. Cowboying is another story. In my mind horses are for riding and mules are for packing. But unless I'm working cows I'd rather ride a mule than pack a horse.
