Is sound genjutsu more powerful than eye genjutsu? After going through this link, I came to a belief that sound genjutsu is far more superior to eye genjutsu.

After recalling the incident of the two Sage Toads' genjutsu and Kabuto's genjutsu, I felt that it was difficult for the Sharingan/Rinnegan users to concentrate on their battle.

So is my speculation true?

Some of the sound genjutsu techniques are listed here:


Demonic Illusion: Toad Confrontation Chant
Temple of Nirvana Technique
Demonic Flute:Phantom Sound Chains
It's not that sound genjutsu is superior. Sound genjutsu operates on a different sense, so that renders doujutsu (eye techniques) useless to escape from it, unlike with illusions that work on vision.

That makes sound based genjutsu more effective on Sharingan users, because they rely on their improved vision powers to counter most genjutsu.
