Homogenic is one of the great albums by any artist. I agree with everyone who says that the first 3/4 are where it is at but that one stands out even amongst those. My order would be Homogenic, Debut, Vespertine, Post.
I think Debut and Medulla are both the same! Like some days I’d prefer Medulla over Debut and vice versa. But Homogenic and Vespertine are definitely my two favourite Björk albums!
