I love both manga and anime but I prefer more to manga as it is produced directly from Oda.
I am not 100% opposing what were presented in the anime and by some of the theorist, but we need to understand that there was always scenes that were not included in the anime and some are added in the anime.
From the video link, we can see 3 three Zoro's scenes. 1st in Sabaody where Zoro lost his way to the Sunny. In manga, there was no fighting between them (or maybe I missed it). 2nd, When confronting with the dragon in manga, it is not very clear if there was aura released from Zoro but the dragon did tremble. 3rd, After Zoro cut Monet in half, Monet wasn't be able to assimilate properly and Tashigi did said it because of Zoro's intimidation alone and not because of any form of haki.
Though, I still want Zoro and Sanji awaken their haoshoku. Just like Rayleigh. Shanks was just a cabin boy and an apprentice in Roger's ship and nobody expecting he will be a yonko from the first chapter yet he awakened his haoshoku even though it was said 'only for the selected' and with the king's trait.
When I watch the Chapter 0, I didn't see Shanks as the future yonko but now I am glad he is part of the yonko.
