A: ...in many ways Powershell is stil king of the shell game [but]...

B: Have you tried nushell?

Anyway... nushell is more similar to Powershell (but AFAIK there is no JIT). My default is zsh (as you have mantioned, because of mac) but I use nushell for few things - it is pretty different from bash/zsh/ion/fish. It is more like data pipeline.
