Superior?

That depends on a lot of factors.

I mean, a Vampire will kill a ninja any day. So they've got that battle won. I mean, it isn't like a ninja has any abilities that a vampire almost naturally doesn't.

However, is a vampire a coller thing to be? Personally, I wouldn't want to HAVE to sleep in a coffin all day long. I wouldn't want to have to give up being able to eat lasagna in favor of something as sickly gross as blood. But, if I were a ninja, it's be pretty cool. I could do all kinds of neat stuff, and I don't think that I'd have to worry too much about vampires coming to kill me anyway.

Also, Vampires are undead. There's all kinds of drawbacks for being undead, even though there are strong points too.

Bah.

I'd rather be a ninja, I'd rather talk to a ninja, I'd rather be around ninjas... So I'd say that ninja is a superior being. I mean, socially. And socially is more important than physically, in my opinion.
