The subspecies are always better than the base:
>Hellhound is better than werewolf
>Cheshire Cat is better than werecat
>Shirohebi is better than lamia
>Holstaur is better than minotaur
>Black harpy is better than harpy
>Jabberwock is better than dragon
>Dormouse is better than large mouse
>Pyrow is better than succubus

I can't think of a single case where the base species is better than all of its subspecies.
