Personally, I see the Van Helsing Dracula because, as Stephen Sommers says, he is quite a 'rock star' type Dracula. And Richard Roxburgh is just that little bit lovely :p
They could talk about women... and lack their lack of underwear, looking at the costumes of the three brides in Van Helsing.

But other than that, definitely Lestat for conversational values... and anything else.
Van Helsing for combat. I'd pay good money to see that.
