Actually Yachiru's Shikai might be more useful and flexible than Tenken because Tenken can only manifest certain body parts at a time and seems really bulky and slow where as Sanpo Kenjuu manifests entire beings both in front of and behind her that mimic every single move she makes and can move as fast as she does.
