Definitely not. Zoros current CoO is not good. He never has a good grasp of his surroundings, people have stolen from him, he’s been caught off guard regularly by people.
Sanjis CoO is much better and will continue to be so. Zoro may fight an invisible fighter, which will force him to either grow his CoO or find an alternative. However Zoro EOS will be fighting Fujitora or Mihawk, strong characters with good CoO, but Sanji EOS will be fighting Kizaru who is so fast he’ll be impossible to fight without strong CoO.
Not to mention CoO doesn’t match Zoros fighting style. Zoro would rather just overpower a character than dodging and counterattacking which shows he’ll continue specializing in Armament Haki.
