Needless to say that Van Helsing is the one at the top of the list.
But, recently I watched another one (terrible) movie called Dracula: The Dark Prince. It had a white haired Dracula, it had a living armor, it had some vampire hunters, including Helsing, and had a puny name for an item that should be used to slay Dracula called "Lightbringer Staff". It even had an EXTREMELLY CASTLEVANIA-looking castle, that was invisible and hidden on the mountains. The acting was horrid, and the plot was terrible. The opening sequence wants to be Coppola's so much, and the effects are subpar. All in all, it made me wish to never have a Castlevania movie.
Speaking of which, do you remember Dracula 2000? The protagonist was curiously called "Simon". Coincidence? I THINK NAWT! And then there is Dracula III: Legacy, where a dude goes killing monsters with a whip.
Are there any other movies in the same vein?
