Wolf. Wolves are naturally shy of humans, and while gorillas are also, gorillas are also much bigger and stronger. If one decides it’s mad at you it will pull your limbs off. Or worse. A wolf will try to rip you apart and tear your throat out if it’s mad at you, but since it’s in a different weight class you might actually stand a chance if you curl up in the fetal position or whack it in the face with a rock.
