[General] If someone is turned into a vampire but freely chooses to never consume human blood, not even once - does that individual gain or lose any advantages or disadvantages to doing this?

This depends on what universe you're in.

In *Buffy the Vampire Slayer,* Angel subsists indefinitely on animal blood, and merely doesn't like the taste.

In *Vampire: the Masquerade,* animal blood is much less potent than human blood, and "vegetarian" vampires must consume more of it.

In *Vampire: the Requiem,* not only is the above still true, but only weak vampires can exist at all without human blood - and particularly powerful vampires consume vampire blood.
