I read Jim Corbett lot and according to him Tigers are the most dangerous cunning animals, Event hunt human just for fun sometimes.
A big male lion do nothing but eats only what lioness hunt and take a big share and went in shade for sleeping do nothing but only protect it's clan from intruding male lions.
So ask yourself whats tougher.
Hunting buffalo, zebra and humans.
Or fighting another predator your own size, often two together, with the same weaponry.
