(Chidori Kireme) - One thousand Birds Breaker
Advantage: This could be best used as a surprise attack, a good example would be using such a jutsu as hidden in the mist to help close into the opponent undetected & then follow up with the series of attacks, other uses to cover the opponents vision could be helpful if you have a doujutsu; Smoke bomb, dust from the ground, affer effects of an explosion, such as thrown kunai with explosive tags.
Disadvantage: It requires the user to close in to the opponent which makes it a hard situation to also get out of if the opponent has a counter ready.
(Chidori Tokkan) - One Thousand Birds Rush
Advantage: The best way to utilize this is by aiming the sword under the chin or chest creating enough force to lift up the user off the ground, at the same time as you could leave the opponent with a sever wound from the blade itself which could leave them unable to avoid the chidori
Disadvantage: Same as before, it is a risky move when trying to reach in close range of an opponent espcially with a hand occupied making it harder to use both hands when trying to commit your own counter.
( Raiton Chidori: Raijin no sakebi ) - Lightning Release One Thousand Chirping Birds: Cry of the Thundergod
Advantage Similar to above, creating multiple slashes towards the opponent can always leave then unable to create a counter due to extensive wounds left by the user which makes it easier to finish the whole attack without a counter
Disadvantage: I would say the same as the others, lemme know if I missed somethign though
