here have some vocaloid and fgo tier lists, might update in the future with more if I feel like making more
specific order means within each tier, from left to right, up to down, is better to worse
non-specific order means I didn't think of who's better within tiers
all these tier lists are of nov 2020, may change over time and fgo will def add more servants
Vocaloid Tier List by Voice (specific order):
Vocaloid Tier List by Design (non-specific order):
Fate/Grand Order Servants by Character (design has some influence on upper tiers, but mostly just how they act, characters not released in NA yet but are still tiered are cuz of the fan comics/memes lol) (non-specific order):
also kadoc S-tier
