Lots of animals display intelligence.... Just because a chimp can be taught to use a smartphone doesn't mean that chimp could engage in electronic espionage. It would be hard to use his breath to fly and as an effective weapon at the same time. What I think it boils down to is the nature of the respective fictions: Godzilla is always written as an unstoppable, indestructible god mode monstrosity, (a reflection of the need of the Japanese to inflate their own egos and secure their masculinity after we handed their butts to them) and Dracula is written as a powerful, corrupt antagonist who gets defeated in spite of the odds against it. Godzilla would win if this became a canon installation. I like subverting tropes, though, which is why I argue for Dracula. At the very least, Godzilla would be mind controlled for a period of time as a vampire before being cured somehow.
