Suna high diff. Temari's wind+ chiyo's and kankuro's poison will get akatsuchi,kurotsuchi and kitsuchi,not to mention kiri mae basically oneshots quite a few of them,deidara already claimed sasori was much stronger than himself.
Onoki and muu may have jinton,but if oyu have noticed,they need to stand still,form it and then fire it,gaara,his dad and the 3rd kazekage arent gonna watch that happen,especially with gaara's knowledge on jinton,all the kages here can fly,and gaara can easily sense muu,who needs to become visible to attack,gold dust and iron sand will prove too much for the tsuchikages to avoid,especially with onoki's little stature,not to mention that all kazekages basically use the same techs,and their attacks are very fast(3rd and 4th kazekage can use magnetic force of attraction to instantly summon gold dust/iron sand,and then repulsion to send them flying towards the kages at fast speeds,gaara's sand is easily one of the fastest things here as well,sand hail+gold dust hail+iron sand hail will definatelly get the other kages,or iron sand drizzle+sand arms+ gold dust hail also works. Sand sensing finds muu and c4 if deidara manages to use it,and temari can blow it back at him.
Temari's wind and the puppeteers poison would take out the kage guards and the other one,sasori beats deidara,3 kazekages beat muu and onoki.
Suna wins high diff.
