there has to be a better way to do this!
I would probably use robocopy for this. It has some switches that allow you to compare folders without actually changing anything (though it wouldn't give you PowerShell objects to work with; just text. It's good for the command line, though.)
There are plenty of examples of this on the web; this one was at the top of my search results: http://improvingsoftware.com/2013/09/09/how-to-diff-two-folders-from-a-windows-command-prompt/
