For all intents and purposes, neither book bearing that title are. Frieda Warrington's book ends with Dracula undergoing permadeath to save Mina and Seward, with Van Helsing helping him. Dacre Stoker's book is a huge mess and should not be regarded as canon at all, especially since it says that Dracula was after Elizabeth Bathory, even though she was his neice and the two are part of the same plot in Bloodlines.
