Kakuzu wins this,,,
-His Doton Domu has the durability to prevent himself from most of sasoris piercing attacks since his attacks wont have the ability to penetrate kakuzus defeneses,,,
-His 5 hearts and katon+futon combo has the AOE and offensive power to destroy most of his sasoris puppets as his puppets simply lack the durability,,, to surivive much of kakuzus, offense,,,
-His elemental attacks coming from all of his hearts allows him overwhelm sasoris 100 puppets,,,
-With his domu defense he is safe from IS,, and can destroy the third kazekage puppet,,, and he also has the physical strenght to destroy hiruko and the evasive speed to evade all attacks from it,,,,
