Dunno how much booru images are representative of "normieness", but this is the data I got in my research the other day.

>1. Cat girl 1140000
>2. Succubus 980000
>3. Fox girl 970000
>4. Elf 810000

Foxes get hard carried by gacha characters(Blue Archive + Azur Lane). Succubus is one of those categories that gets a big boost from random characters in costumes, similar to cow girls, mermaids and rabbit girls.
And Lamia were in fact the biggest option for official game at 6%. That is mostly explained by someone uploading all the MGQ art and the fact that gacha players don't contribute to their community by uploading rips of game assets.
