Don't be stupid....
Sasuke has many chidori variations...he had them before Naruto did actually.
He has chidori senbon which is like WSRS which shuts down your network (black lightning would be worse)
He has chidori spear which can go up to 15 meters and also can be opened with multiple spears (worst with black lightning)
He has Chidori stream which he can use with his body, possibly like Raikage's shield.
He has chidori current which he can use on the ground
He has Kirin
He has chidori sword
He has regular chidori
He also has amaterasu chidori...which is but isn't canon because he did use amaterasu with his hand in the form of chidori
Also this doesn't mean anything, having more variations doesn't mean anything. Rasengan will not stomp Chidori...if anything it'll be equal, Sasuke is using his power and chakra not of other beings like Naruto.
Rasengan is suppose to be superior to Chidori, but Sasuke is so strong that he's made his chidori equal even to that of wind style jutsu's.
I'm not favoring Sasuke, but simply using the facts and be
