My niche use case is that since fish comes out of the box with a whole bunch of very nice features (syntax highlighting on the shell, really good autocompletion) it's easy for me to stick it into the set of shell scripts I use to turn a new Ubuntu VM into a dev productivity machine. [1] I could probably get Zsh to do all the same stuff I would want fish to do out of the box, but it would make reading through and reasoning about the shell scripts more difficult for third parties to audit, who may not be familiar with either tool before they try it.
