So fish comes with nice defaults. It could happen that you have a complicated zsh setup, then migrate to fish and you find the defaults are fine. The fish scripting language is nicer (more logical) than the zsh one. That's because zsh needs to be Bourne-ish for historical reasons, and fish has decided to deviate from it.
