I’ve seen both, Frieren twice now after rewatching it with a friend and ATLA many times including when it was coming out. I liked Frieren but I disagree that it’s the best storytelling. I know people like it and I did too but 9/10 for me. Bocchi the Rock and Dungeon Meshi are my only 10/10 shows so far, and of my 9/10s I like Makeine and Dan Da Dan better than Frieren. Maybe season 2 will bump it to a 10 but for now it’s in 5th place for me.

ATLA is one of the best shows ever made though, I agree with that. Looking forward to the new show.
