Which castle allows for the fastest development?

For many years now, I've believed that the most consistently and easily developed Castle is the Castle itself, because it only requires money, wood, and stone as resources, and these are available on all maps... as a result, by the second week, you have 5-6 horses that gather money and resources for everything else... The Swamp is also good, but all other Castles can run into a shortage of a particular resource (not enough crystal for Behemoths, etc.) and sharply slow down development... IMHO.
