Dungeon Meshi is good because it's Dune for DnD nerds.

You go in expecting a light-hearted fantasy cooking show and then it slams you with a masterclasss in worldbuilding, and soon you're knee deep in ecology, politics and culture; and thinking about how all these things intersect and affect each other. It's catnip for communists.

I like it better than Frieren just because it's a more coherent/focused story- Frieren can get a bit monster-of-the-week/shonen tournament arc at times, which I guess some people would consider a strength in its variety but that's kinda not for me. (Also I have some qualms with the way the demons are portrayed in Frieren).
