Not the original commenter, but I do everything else in bash, and zero things in PS. Why would I want to remember which shell runs which program best?

That makes sense, however if you are Windows user, bash is not an obvious choice for primary shell there.

I don't think that is correct. If you install WSL you are not a typical Windows user.

I didn't mention "typical" Windows user. WSL will always be a second-class citizen in Windows, so if you are power user trying to improve your performance, what's the point in choosing a second-class solution after choosing this OS? Learning one more shell, just like learning one more programming language, has some benefits.

Because I like Windows for myself but my company uses Linux based servers and bash as our shell. It's not just about ME switching to PowerShell, but getting 30 other people to do it too. Not gonna happen.

Because compiling the Linux kernel doesn't? And well, that's another big thing with WSL, you can't share files.
