Mules, hands down. I have both, I use my horses to gather/work cattle. When it comes to the mountains or trail riding local, I'm on my mules. My wife made fun of me for years. I let her ride one after we broke him really good. He is about 13.2 hands & gaited, she took him away from me! Mules are sure-footed, do not spook as easy & way smarter. They will not do anything to hurt themselves. You can make a horse do anything you want. You have to convince a mule it is safe. This year I got a haflinger mare that I'm breeding to my Jack. I think I'm really going to like that cross. I do recommend raising your own if possible. That way you know what you got. Mules need to trust their master. Once they trust you, they want to please you.
