The world record bear kill for the longest time was held by a young Inuit woman who discovered a polar bear stalking/trailing her as she walked home along the edge of a frozen lake, at night, in the shadow of the forest to conceal herself from predators. She ducked into the woods when she rounded a bend and lay in wait for the bear following her. One-shot with a 22lr to the temple downed the bear which she then followed up with several 22 rounds to the same weak spot of the bear's skull when it was down.
I would choose the weapon that best suits your nature, regardless of the caliber. Or what anyone says here.
Choose a gun that suits YOU and what you anticipate. I don't reckon I'm going to get involved in a long-range shoot-out as a normal, regular Joe walking around town so I have a 380. 13+1 that suits me.
