The main thing that both anime got in common is the fact that they are both about vampires. Some vampires wish to do harm and have some sort of evil plan but the main character(s) tries/try to stop them of course. Hellsing Ultimate has more action than Vampire Knight Guilty. Vampire Knight Guilty on the other hand is about more than just action and bloodshed. It also involves romance and therefore Vampire Knight Guilty is a shoujo anime while Hellsing Ultimate is a shounen anime.
