Vampires. Mind over brawn every time.

Just because vampires can't go into the sunlight, doesn't mean they can't protect themselves during the day in their own defensive bunkers. Assuming vamps have to sleep, they just setup shifts. Any defenses humans have today, the vampires would have. Defensive positions usually have the advantage over the attacker.

As far as 'human blood' goes, depends on what "rules" you want to setup. If the vampires are alive now, you have to assume they have a supply -- it's either synthesized blood producing machines, or they slowly drain blood from captured werewolves. Of course bodies produce new blood cells, and vamps only drain enough to keep everyone alive.

Zombies vs vampires - vampires have all kinds of guns.

Werewolves vs vampires - vampires have silver tipped bullets in their semi-automatic weapons. Plus when human werewolves change into werewolves, it's generally accepted their intelligence is greatly diminished. Vampires with body amour, nightvision, silver-bullet semi-automatic weapons combined with human intelligence would have a huge advantage.

Vamps wouldn't even need it, but V also accepts vamps have the power to turn into fog. A weaponless vamp could be surrounded by 20 werewolves, and simple turn into fog and escape.
