And it is really different context.. before just a clash of haki and this chapter clearly just zoro adCoC haki not haki clash..
But Zorotards would denied it bro, because they want to push their agenda, instead of the logic, Zoro finally use adCoC to end Lucci or the battle will go longer (as the naration and Sanji comment) cause before he can not do it without it.
Zorotards will always be zorotards, dishonest people
