raikiri is stronger, enhanced version of regular chidori

What he said! ^^^xd! besides the justu the raikage is using is on a way higher level than raikiri

Chidori is more closely related to the rasengan but more sloppy because it is not refined. The Raikiri is more of a blade enhanced version of the Chidori.

At least that's what I've always understood it as.
