After getting frustrated with how unusual and convoluted BASH syntax tends to be, especially with involved scripts, I've tried almost all of the alternative shells: Elvish, Fish, Oil, Xonsh (Python!), Emacs's eshell, and even the Haskell-based shell repls like Turtle and Shelly. The only one I really stuck with was Nushell. It's friendly, pretty, intuitive, easy to read, heavy on pipes, and super powerful for data analysis. Plus it's modern replacement for a lot of tools, like `ls`, `jq`, `curl`, and so on. Writing a little command-line program is a joy in Nushell.
