I am not really into shells, so my experience is very novice when it comes to shell scripting, but I’ll let you know that I went from bash to zsh, and then I also tried fish but went back to zsh because I felt that it was superior. Generally I find zsh to be little easier than Bash, but bash isn’t bad in itself too. I disliked having to learn new syntax for basic shell scripting for fish the most I think.
