The Praetorians slaughter hypaspists quite easily as well in the same settings. They lost 10% when I tested. I don't know about other elite foot units but I'm pretty sure the Praetorians will win with various levels of decisiveness. Part of this is due to the game, because at least concerning the hypaspists, the Praetorians had double the number. And the other part is that the Praetorians are several hundred years later and therefore able to receive expanded training and equipment than these units in the 3rd century B.C or even earlier.
