I completely agree with this.

I recommend people Zsh: it's very familiar, scripts copied from the internet will most probably work and they have lots of flexibility to adjust it to their needs.

I personally have a Mac with Fish installed, I don't enjoy the process of sharpening my tools, I'm willing to give up flexibility in exchange of great defaults. It's the same reason why after I learned how to use a sharpening stone, I ended up buying an electric knife sharpener.
