The difference between them is simply Kakashi has developed it further. Same principles. They have separate pages in the databook and separate ranks as well as you mentioned.

Not only that, Sasuke makes a point to correct Deidara during their fight; Deidara calls Sasuke's jutsu "Raikiri," but Sasuke corrects him saying it's only "Chidori.

Where in the world did you get the first tidbit from? A jutsu's rank certainly denotes its power, lol. Difficulty yes, but power as well. The Raikiri is certainly stronger than the Chidori. That's like saying an S-Rank fire jutsu can be defeated by a C-Rank one. Yeah... no.
