is it worth it?

No, this is: http://xon.sh/

None of them are.

If they don't even have a bash mode they are basically already dead.

Even zsh, with all its language enhancements like nested string manipulation, and even "more corporate friendly" license hasn't deprecated bash.

Why would they need bash-mode? Any scripts that you would execute have a she-bang anyways: as long as you have bash and sh installed all system-scripts run perfectly fine.

That's like saying as they don't also have a mode to be actively worse, they aren't worth it. Although for the record, xonsh does have a way to source/execute bash files.

As an interactive shell, yes. It's great in that role. As an alternative to sh/bash for shell scripting? Not really. If you want a shell-like scripting language, use Tcl (easy), scsh or es (harder).

sh > bash > ksh > everything else

sh is defined in POSIX and works across systems, so it's good for scripts that need to run everywhere
bash is de facto standard in Linux, the most common Unix these days, so it will work 90% of the time
ksh is de facto standard in every surviving commercial UNIX, so it's good to know if you maintain these systems
everything else is either meme shells you'll find on rice boxes (zsh, fish, ...) or utter trash that only survives because it's a part of "tradition" (csh and tcsh). fuck BSDs, man.

except when it doesnt, when build scripts and other similar things FUCKING ASSUME everybody is using Leenoox and lo, you can't run it unless you install bash!
