I use pirate sites over Crunchyroll not because I don’t want to watch ads/pay, but mostly because I like the pirate sites better. I just don’t really like Crunchyroll’s website. Aniwave. to was the greatest imo until it got shut down :(

And of course the pirate sites have much more variety, Crunchyroll doesn’t have everything, but you can bet money that pirate sites will have all 4 seasons of show X, plus the summary season where they recap, plus the chibi side show, plus the 2 anime movies.
