greetings..the team examples that you are showing are both good for kakuzu i think..each team can provide a unique combination of talents which it can give a different result....

the first team example is splendid indeed...kakuzu and minato can be a fatal duo since minato can go on a wonderful harmony with kakuzu. he can aid on triggering kakuzu chase attack and causing high damage ... having both of them on position 1 & 2 will be giving you the chance to stop your enemy mystery attacks...and with each time minato successfully perform a standard attack combo his mystery cool down will be reduced... and this will be making minato a serious problem while he is still alive....their attack power will be heavily supported by your main and gaara surely...

....................................................................

the second team is good also but if i am not mistaken ..it cant be giving the same result on p vs p battles as how the first team does...this team depends on kakuzu mostly while having the rest of the team for supporting..it can make kakuzu attacks highly dangerous so i assume most of your power weight will be on him...yet if he will get controlled by a strong debuff your team will be having harsh times to deal with this problem i think...yet it can be good for fast eliminations...

both teams are having the buff advantage that will rise your units damage and endurance potential...

first team example is having barrier support which it can give you a chance to turn the battle advantage to your favor ....mostly i think it can be great on p vs p battles

the dreadful threats for your teams might be buff removing ninjas and control ninjas and super armor removing ninjas as well...

hope this may aid you on making your decision....wish for you fruitful efforts and splendid results !

best of luck....
