Well... we're back to almost everyone choosing one option over the other. If you listen to the podcast, we were no exception, with only Sean choosing to be a giant (and he only chose that because of a cartoon giant from his youth).
Reading through the comments, it seems like there was a clear preference for the practical benefits of invisibility (namely sneaking and being naked with no one knowing), and an aversion to accidentally crushing people and property as a giant.
Go figure.
