I've never really seen PowerShell beyond minimal commands, but after seeing the parent, I definitely think it has the superior syntax of the shells. Especially for scripts.
Then I tried it and I strongly dislike it. The syntax is clunky, it's really no better than popular Unix shells at being a "real" programming language, and yet it's not as good as they are at being just a shell either.
It also just doesn't feel like a quality product. On my work Windows laptop, Powershell will sometimes not quite bother flushing after it starts, so I get the banner text and then... I have to hit "enter" to get it to finish up and write a prompt. In JSON parsing the provided JSON parser has some arbitrary limits... which vary from one version to another. So code which worked fine on machine #1 just silently doesn't work on machine #2 since the JSON parsers were changed and nobody apparently thought that was worth calling out. If you told me this was the beta of Microsoft's new product I'd be excited but feel I needed to provide lots of feedback. Knowing this is the finished product I am underwhelmed.
That’s independent of the shell, and is I believe a bug in the terminal emulator. There is an open source Windows Terminal you can separately install and that is so much better.
As it turns out, the reason that "curl ..." doesn't work is because it pops up a window below all of my other windows saying that certificate revocation information is unavailable, and would I like to proceed. After that it does download my web page!
YMMV (and obviously does). I think that powershell is night and day better than bash (etc) as a programming language.
I generally don't like MS software, but their commitment to back compatibility is worth calling out.
