Which is better, HMS Pinafore, The Iolanthe, or Pirates of Penzance?

-Just curious as to which Gilbert and Sullivan operetta anyone finds interesting / awesome / whatever. n.nI know nothing about "Iolanthe", but "Pirates" and "Pinafore" are both great, if implausable,

works. If I had to choose between those two, I'd pick "Pinafore".
