My own arc rankings:
S1
S3A
S5B (The sole exception, where I like the B half more than the A half, thus far.)
S4A
S2
S3B
S5A
S4B (This is my least favorite, because the character assassination of Snowing was beyond ridiculous. The Queens of Darkness were also a huge letdown, as they were poorly developed and overcrowded. Not even Cruella or Isaac could save this arc.)
