I know how that feels. 
I use both bash and powershell, they each have their perks. For working with windows objects powershell is certainly better by far. However I can pump out little things in bash far faster (something simple like finding all files of a type in a directory tree then matching a regex inside of them to get a list of matchers is definitely longer and more unwieldy to type in powershell than bash by far). Right now I have one powershell window and 4 bash windows. Though for anything that needs to last longer than something ephemeral I generally write it in Elixir. Elixir actually makes for a really easy scripting language for the people here. We have quickly turned into an Elixir shop (one of the reasons they hired me was my almost 10 years of erlang spare-time work).
