I haven´t got the game yet (I´ve already ordered it, but it will take a couple of weeks to come), but from what I have learned from rulebook, it seems to me that the Queen is far better than the King. In terms of resources they are almost the same (OK, the man´s got 1 more, but their type is given), and the 2 soldiers don´t seem to be equal as all those extras you get from the Queen (VP´s, looking at the attackers´ card).
Did anyone make a different experience?
