I'd say they're close, maybe with SSJ3 being a bit stronger but since it has more strain I'll say SSJ2 Goku wins.
SSJ2 Vegeta, SSJ2 Goku and SSJ2 Z-Sword Gohan vs Gray Buu
Buu Saga versions all around.
Here we go, the only 10 manga I've read ranked from my favorite to least favorite.
Jujutsu Kaisen
Berserk
Dr. Slump
RaW Hero
Nanatsu no Taizai
Tokyo Ghoul
Gantz
Grashros
JoJo part 5
JoJo part 6
NNT, Tokyo Ghoul and Gantz could be shifted around in any order tbh.
