It is totally unfair to compare both things
because one of them is attack depedent on Key-key-genkai
and Another is an 'A' rank jutsu founded by Genius called Forth Hokage
rasengan
a bigger stronger version naruto made himself to improve his rasengan
Stronger than the Chidori (in no particular order): Thunder Clap Susano'o Mangekyo Sharingan Tsukoyomi Flying Thunder God Technique Rasengan Rasen-Shuriken Izanigi Summoning Jutsu ~Many more Stronger than the Rasengan (in no particular order): Everything in above answer minus the Rasengan itself.
it depends on the user.
Because chidori and rasengan has the same powers. You might think rasengan is stronger but they are the same thing! Chidori and rasengan are both specials. It doesn't matter how powerful it is it matters how the wielder uses it.
The Lightning Blade is generally considered to be stronger than the Rasengan. The Lightning Blade is a high-speed thrust with a focus on piercing power, while the Rasengan is a spinning ball of chakra with a focus on impact force. Ultimately, the effectiveness of each technique depends on the skill and power of the user.
