As mentioned, the Mythic Legions has a knee articulation over the Figma, the Figma has better range in its ankle (however you call the joint below the knee), the figma allows a few degrees of side to side movement in the shoulders which are simple forward/back swivels in the Mythic Legions...
The most amazing horse articulation around that size seems to be the upcoming Elena from Arcanadea model kit by Kotobukiya.
