What vampire series novels do you like?

The following are vampire fiction novel series. I have read all of the books in the Twlight Saga series several times and have just finished the most recent book in the House of Night series. I am looking for a new vampire series to get into, so please help me by rating the following series. Choose 1-5 for each series with 5 being the best or choose "I don't know" if you haven't read them. I have included Twilight and House of Night just out of curiosity.
