I feel like they are pretty comparable in concept? Not super identical but old ass ancient vampires who are basically godlike monstrous disasters, have their own clans(Or Prince/Princesses and lesser vampires for DAA), the basic curse of vampirism seems more in line with the Dead then a TA, the whole concept of Diablerie kind of makes me think of taking the position of an Ancestor and how some of the clans came to power. And they are probably tainted as fuck which while not the same makes me think of DAA since they are walking curses. Most importantly, they are shrouded in mystery and are mostly the boogeymen figure of their setting. And we know dick about most of them just like DAA. I guess we know more about them than DAA but they still kind of tickle the mystery vibe and the larger than life feel since they are mostly setting plot devices.
