It's a wonderful tool for me in a Windows environment/shop, especially with how it works well with all the Windows and Microsoft administration systems/tools we use.

Personally, I'm less interested in any language's hypothetical merits than how it fits as a tool for what I need to accomplish and ease of future maintenance when the script/program/automation inevitably needs to be adjusted.

All that said, I can't think of a legitimate reason to use PSCore on non-Windows hardware unless you're just really familiar with PS and literally nothing else. Even then you're better off taking time learning a better tool for that environment.
