It's only recently that the DAZ human models have become more or less nice. The worst looking body parts were traditionally hands, feet, hair, and faces. MakeHuman bodies were always even worse than those by DAZ. Haven't come back to MH for years though so no idea what they have in stock now.
What concerns rigging and posing, you can always rig, pose and animate any well-proportioned T-posed human model in general-purpose 3ds Max or Maya or even Blender using their stock bipeds or customizable skeleton hierarchies, so there's no real need for specialized and restrictive-use software as DAZ.
And there's a ton of free biped bone animations on the net including digitized mocap sequences like idling, walking, running, swimming, boxing, dancing, etc. etc. etc. for various types of known standard skeletons.
