None of them, generally, I don't find them good to the story.
I evade them like the plague, im not talking about the ones you give them specific traits of yourself, like being scared of insects or being shy with the boy or girl you like.
it's always the ones that ruin the immersion of the story being told, like if I see a guy with quirky personality in the middle of a zombie survival setting, a place where you can easily die, I know that's the self-insert.
Its a dark place, people die, people get sick, and other atrocities just happened on the story.
There is no place for a self-insert in an apocalypse, terror or even conedy. It just a character that doesn't belong with the tone of the story.
