From the most recent discussion about the best anime worldbuiiding, my choices continue to be Made in Abyss—as in I agree with the article in this case—and Violet Evergarden, but Witch Hat Atelier is getting to be a contender.
FMA2003 as well. I love that we got two very different worlds from that manga.
Brotherhood had a better ending, but the original did more interesting things with the homunculi.
