I don't really have an overview of what's on Cruncyroll, but my top 10 in general would be:

1. Death Note
2. Naruto
3. Future Diary
4. Hunter x Hunter
5. Naruto Shippuden
6. Avatar: The Last Airbender (sue me)
7. FMA: Brotherhood
8. One-Punch Man
9. Monster
10. Steins;Gate

Though it's been nearly a decade since I've watched some of these, so the ranking's a bit shaky.

i don't know if they had One Piece. if they have it, then it's the best anime on the service, and that's not for discussion

Food wars

@VersusEvil what do you think ?

Interesting taste : D

So true. One Piece is so impressive in the last years!

Berserk
Cowboy Bebop
Bobobo-bo bo-bobo (Sadly, not on Crunchyroll)
Space Dandy
Another

Gurren Lagaan
Cowboy Bebop
Deathnote
School Rumble
Genshiken

Right now my top 5 are:

How a Realist Hero Rebuilt the Kingdom
Maoyu
Demon Slayer: Kimetsu no Yaiba
Mushoku Tensei: Jobless Reincarnation
My Dress-Up Darling

This changes depending on my mood, but is what it is right now.

I only watched Food Wars on Crunchyroll, but I would say anime-wise:
- Full Metal Alchemist: Brotherhood
- Death Note
- Great Teacher Onizuka

I would watch these all the time
