I'm not exactly sure. I use xonsh, but pretty much exclusively because it has better autocomplete and can serve as a calculator(Type 4 *3 in bash and it won't work without some calc command). For actual scripts, I use bash. But then again, I don't write shell scripts. I might have a 5 line logic free script here and there, but pipes and variables and loops and globs are not a regular fixture in my life. I just move straight to Python if I want to program something, and I almost never have any need for a quick ad hoc script. But some people do real work in shell. And they like to program interactively. And bash is not the nicest language. I don't think any shell is that great, they all make compromises trying to be both a UI and a language, but bash is especially not great. I wonder if the people who like shell in general would like a FORTH based shell.
