i went on an exhaustive search once for this and the answer is anything labeled yuri or shoujo ai is made for neckbeards, but that isn't surprising

better f/f relationships, as with better m/m relationships, tend to be in works where romance isn't the focus, which usually means it won't be labeled with any of those. looking for romance manga/anime is digging through the no-returns clearance bin for the same reason you don't go hunting through the bodice-rippers for good books
