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. No it doesn't.

FTG is ranked as Class S, but it doesn't even have a power output.

Also, Rasenshuriken has been described as beyond S-Class, yet failed to overcome the Third Raikage's Lightning armour which is only B-Class.

So yeah. Basically what @Elve and @Omnibender said.
