Since when was a lightning bolt wide spread? Kirin is real lighting not manipulated chakra.
look at chidori. the way it is used, and shaped, its an attack used for piercing through objects, thus it has a focused point, in fact the stronger the thrust the deeper and more powerful the impact, when it does land, there is no radius, theres just the small hole/wound/etc as was shown when he pierced the water tower in part 1. Kirin on the other hand is not just a simple lightning bolt, its a giant bolt of electricity, in the shape of a creature, when it lands, the destruction from it is wide spread as shown when it destroyed the entire building. Im saying, dont say that just cuz a chidori pierced through A dont mean that he cant tank Kirin, Im not saying he cant or can, but thats a bad comparison.
