Werewolf girls are objectively superior to vampire girls. A vampire woman is the vast majority of the time a barren dead thing.
Vampires are also considered demonic and an analog to Jews so even if you knocked one up your bloodline has been cursed with evil.
At best you'll have one dhampir child that while strong, you'll most likely only have one given given the difficulty of knocking up a corpse.
A werewolf woman is the perfect wife. She is a hunter, a warrior of the wilds, and a guardian of nature and it's balance as it's apex predator.
Unlike a vampire girl, a werewolf can get pregnant with MANY strong werewolf pups compared to just one half breed child that will never be accepted by either vampires or humanity. Your children will be welcome as true wolves.
Imagine how your future grandchildren would react to knowing their grandfather was just normal human guy who had such Chad energy a tomboy werewolf woman NEEDED to be bred by your cock.
They're gonna be like "damn what a fucking lad."

Wolves are also very important in Indo-European myths like the mother of Romulus and Remus.

TL;DR Werewolves are the Aryan choice.
