Yes, that Dracula story is one of my absolute favorites, very well written and illustrated. I'm amazed it isn't much more well known, both for its outstanding quality, and for it being the first Bissette/Tottleben collaboration.
I love the sense of an eternal cycle in the story, and the pervading evil. That even the priests in the story are committed to grisly tasks to rid themselves of the vampires and the Ottoman Turks. But even these are portrayed as just part of a larger eternal history of war, violence and struggle against the supernatural.
The BIZARRE ADVENTURES anthology series and preceding MARVEL PREVIEW issues were consistenetly good, and contain many of my favorite stories.
You may or may not know that there was a preceding "Dracula" story by Marv Wolfman and Neal Adams, from the magazine
DRACULA LIVES 2, out in 1973:
