Honestly, fish just has a much nicer user experience OOTB for me than anything else I've used. The way it colors commands, arguments etc automatically was what sold me on it more than anything.

It's an excellent shell for interactive use. I would recommend writing actual shell scripts in Bash or good old POSIX shell however, if for no other reason than LLMs generate much better Bash code than Fish code. Zsh is similar enough to Bash that I haven't heard of it making much difference.
