Fish has taught me that I should strongly prefer shells with batteries included when it comes to interactivity, and Elvish has beautifully demonstrated how that can be taken even further with things like its built-in navigation mode. PowerShell's big weakness, imo, is that it lacks that emphasis on interactivity OOTB, and configuring it back in often results in astonishingly bad performance. That said, the language is way better than any traditional Unix shell, and the ecosystem of libraries and scripts is insanely comprehensive. Together, these factors make for an absolutely top-notch scripting experience. This is definitely one of the the biggest sources of inspiration for most next-gen Unix shells afaict.
