Your scan showed that a smaller slug had a "shitty" aoe, but you still haven't debunked the claim that a 100% katsuya's acid would be larger than the previous smaller slugs (even the one you showed).
Katsuya stomps. This isn't even a debate. Its smaller form survived CT's crushing weight from inside, along with Kurama's 8th tail chakra release without a scratch. But Sakura and Tsunade's punches kill it? It isn't happening.
I have actually come to the conclusion that the Lady Sakura could solo,
-Her monstrous punches broke off Kaguya's horn. The horn is tougher than the rest of the body, which took 9 bijuu rasenshurikens with minimal damage. Therefore we can conclude that Sakura's attack is stronger per unit area than the 9 bijuu rasenshurikens,. Katusyus best feat is tanking ST, which is absolute fodder compared to those attacks.
-The main issue with Sakura against the higher tiers is her speed, but this isn't an issue in this match, as all of Katsuyu's attacks are dodged!(avoided the sea of acid in that dimension, and saved Obito)
-A continuous barrage of Kaguya horn busting punches absolutely demolish the Slug.
