Kotoamatsukami VS Tsukuyomi

[Dark Riku]

KA is more powerful.
Tsukuyomi is more suitable in a fight though.

 

[Naruto99Uzumaki]

ka solos everyone plus rikudo sennin

 

[Your Creepy Stalker]

Tsukiyomi can repeatedly mindcrush enemy's. KA has a 10 year cool down. Unless your enemy's will agree to wait, Tsukiyomi is better.

 

[Joseph Gomes]

KA is more potent, tsukoyomi more useful in fight

 

[naruttebayo]
