From Bash to Zsh there's very little difference it's a mostly frictionless switch. That being said I would not recommend it because in my experience it's just another thing to configure.

Personally I hate configuration these days, not tryna maintain a litany of dotfiles in my home folder when all it does is frustrate me when I ssh into a different environment or switch computers and things aren't just how I like them.

I switched a while ago and it has some slightly nicer autocomplete features and things like that, which I now miss in bash

Things I use ZSH over bash for:

1. running an ls whenever I cd into a directory chpwd() ls -Ah --color=auto
2. fish-style autocomplete using zsh-autocompletions.

Nothing else. I didn't want to use bloated frameworks like oh-my-zsh and don't really have any use for eyecandy.

My prompt looks like PROMPT="${NEWLINE}%F{blue}%d${NEWLINE} $ %F{white}" and I find that's clean enough.

It's hard for me to leave the comfortable familiarly of bash.

I use fish for when I'm using git because of autocompletion and niceness, but mainly stick to bash bc it's everywhere. I tried https://starship.rs for awhile but it's honestly a bit too flashy and distracting

fish is just better as an interactive shell and doesn’t require me to manage gigantic configuration scripts. I write shell scripts for sh out of inertia. I’ve never seen a good reason to use zsh.
