Hyenas are far better than lions. They eat all parts of their prey, even bones, their hearts are better suited for the size of their bodies in comparison to lions, they're far more intelligent than lions, they're more social than lions, are one of the few mammals able to survive rabies and have an excellent immune system, can learn to live with humans and that applies even to wild populations of hyenas(see city of Harar, Ethiopia).
And personally I think they look far more majestic than lions.
