IMO one of the biggest advantages of zsh is it's almost 100% compatible with Bash. If I'm in my shell and want to run an adhoc command with a for loop I want to do it with Bash's syntax, not learn a new Fish syntax. Having to manually drop into `bash` to run a bunch of commands is too inconvenient. Also you'll find most examples online using POSIX shell or Bash compatible syntax. You can carry over those to your dedicated scripts and adhoc commands. Your knowledge becomes shared.
