Werewolves get my vote for a nmber of reasons. First and formost the only real weakness in this fight is they turn back to humans once day roles around. While this will stop the Werewolves, the same situation will kill the Vampires. The Werewolves only other weakness is Silver and that is increably unlikely this will come into play for two reasons. For one Silver on it's own is farily rare let alone silver weapons and it is increably unlikly the Vampires will get ahold of any Silver weapons. Another reason is  depending on the type of Vampire, silver is a weakness of theirs as well. This may or may not actully come up, but the fact the getting ahold of silver weapons alone is unlikely is enough for me to think is won't really be a factor in this fight.

While the Vampires have superior intelligence, the Werewolves have animalistic instinct on their side, which is just as good in the scenario of a fight. Then their is the the physical traits of the Werewolves. Werewolves are generally seen as stronger and more durable than Vampires. This combined with pack mentaillty and killer instinct gives the Werewolves the edge in my opinion.
