Which Configuration Manager PowerShell Module should I use?

If you use PowerShell with Configuration Manager, you likely know that there are two PowerShell modules named ConfigurationManager.psd1. One is located at %PROGRAMFILES%\Microsoft Configuration Manager\AdminConsole\bin and the other one is located at %PROGRAMFILES%\Microsoft Configuration Manager\AdminConsole\bin\ConfigurationManager. If you are trying to figure out which one to use, the %PROGRAMFILES%\Microsoft Configuration Manager\AdminConsole\bin is the most logical one. The other module just references the first one as a nested module with no additional benefits.
