Both characters have full chakra!
Battle to the KO!
Let the opinions fly in! GOOOO!!!!!!!
(Please breakdown your opinions properly,and not just state who because they possess, such and such of a power. Try and give fairplay to both sides, explain what both sides may do well and not so well and ultimately why you have picked the character you go for. This is so no one talks dismissvely about the characters, especially for Kurotsuchi, acknowledging the fact that she is not a huge player in the series.)
(To make it as fair as possible, I will go with the 4th Shinobi War versions of both characters, because if its taken from the point of view in the time where Boruto:The Movie takes place, its hard to distinguish who's more skilled, as we don't really have an indication as to how powerful Shikamaru is at that point, even though he seems to be in an advisory position to Naruto, whereas Kurotsuchi has become the 4th Tsuchikage by then, which would mean or at least indicate she must have gotten stronger since the war.)
