What is the best and worst anime you ever watched?

I've been wanting to binge watch some new anime for a while now

The best for me would be Code Geas, and School Days would be the worst one for me

best: Fullmetal Alchemist Brotherhood, this was the first anime I ever watched but still holds up. But if Vinland Saga stays as good as the first season it could beat it for me.
worst: Berserk 2016. This one is personal because I love Berserk but they just got everything wrong in the 2016 anime it's so bad

One piece best . Basquash worst

Best: I think Mob Psycho 100 is one of my personal favorite
Worst: Assassination Classroom, I stopped ep 8 or 9 because it was boring
