Others may say say why is zsh interesting when we have rc? Or why is rc interesting when we have bash? Others may ask why is bash interesting when we have tcsh or pdksh?
I would like to know what is interesting about a world with one shell for every user?
I tried to get started with both. For me fish was by far the easier & more friendly starter. For shell powerusers zsh might be offer more options and less pitfalls.
One thing I have found with prezto (as well as oh-my-zsh) is that over time, starting up a new terminal window can take a while. On the other hand, when I tried fish, I found certain aspects of it to be sluggish (autocomplete, for example).
