DAZ Studio vs Iclone. The lesser evil?

Sorry, I don’t understand this point, could you please clarify? I’m very interested in animbp IK for stuff like dynamic foot placement, but I could not find anything except overpriced ikinema that could properly handle Genesis skeleton. Basically, you need IK with constraints (bend bones should not roll, roll bones should not bend), which is not available in UE right now. Or it is available?
