Actually there's plenty of other differences too.
Lycanthropes are cursed creatures of other races, can't control their mind or body easily when in animal form and can give others their curse.
Thirions are their own race of small stature, can control their animal form and can't pass their Thirion abilities to others.
But FFF:R is a reboot so whatever might be true about FI Avbaroy won't necessarily be true about this Avbaroy anyway.
