I use Fish shell and while it is pretty nice on its own, the fact that it is non-standard does cause problems. Many times you will search for something online and you’ll find nice bash results, which either you will have to execute directly in bash or modify to work correctly in Fish.
I don’t think all of Fish’s design choices are the best, either. But for an OOTB experience, it is nicer than either Bash or Zsh.
