Which anime has the best cast?

for me its got to be either gintama,one piece or monogatari

what do you mean by cast ? can you explain

sword art online is one of the best example to cast setting and introduction done by any anime but it varies by the genre.. SAO is isekai genre so its best among isekai, if you care to provide more details i will help you with some good selections..

Ranking of Kings has a pretty legendary cast

The monogatari series cast are great. all bring their A game

Prolly demon slayer ig or jujutsu kaisen cant tell

One piece easily takes the cake for best cast.

for me its got to be either gintama,one piece or monogatari

check dab comment psl not animemon

Code Geass is the best in my opinion.
