Sasuke would never use chidori against rasenshuriken, he knows the elemental weaknesses. With his sharingan he would see the wind element and the scale of the jutsu, if he was stupid enough to poke at a rasenshuriken, wind will diffuse lightning and Sasuke will be left being ripped apart by a million wind cuts left in a crater to die. Naruto would be safely untouched as his rasenshuriken is ranged. If anything Sasuke would use a fire jutsu to counter, or dodge.
He isn't gonna be like Napa trying to catch Krillin's destructo disc
