Other than for man, it's a six of one half dozen of the other. Predators won't take on a healthy full grown animal. They take the weak out of the herd. No way is a lion or a hyena taking a healthy water buffalo. Even the smaller antelope, they stand a chance of getting their face kicked in. Or, spending more energy than they gain chasing a healthy one down. I watched a documentary on wolves once where a scientist studying them, watched them separate out what seemed like a healthy caribou bull. They passed up young animals and females, but didn't bring them down. The guy went back and watched his film to see what made them take that bull. A single slip on the ice. Once he saw it, he could see all the wolves focus on that one animal. He had to watch his film a number of times to see it though.
Conversely, being a predator may be the better side, but it ain't easy. One wrong move on your prey and you might be done. You gotta be strong and take what isn't easy. Not strong enough or not in the mood isn't an option. Not just for the individual, but the pride or pack. They depend on strong members. No easy life.
Also think about different predator levels. Unless you're the apex predator, life is just as rough. Coyote packs kill foxes, Wolves kill coyotes. Grizzly bears will run wolves off their kill until it eats what it wants. Black bears don't fare so well with wolf packs. But, they certainly won't make a meal out of one. Everything likes to keep a wide berth of wolverines.
