I like vampires overall. They can use powers without transforming, the lore surrounding them is awesome, and it adds a bit of a challenge to the game. For transformation, I think werewolf wrecks vampire lord. The werewolf feels better, looks better, and is stronger in my opinion.
Maybe... maybe not....
To bad I dont a PC to run Skyrim. If you do manage to do something like make a video outlining the story and what not. I would love to see what you had planned. In my opinion the greatest place for a Werewolf pack to live would be somewhere in The Rift.
On the contrary Vazgen! Sinding is a Werewolf during I'll Met By The Moonlight and there are others during the Companions quest that were captured by the Sliver Hand. Then in the Dragonborn D.L.C, the hunters at Frostmoon Crag were also werewolves. Also, in Underworld they aren't Werewolves, there are Lycans, Werewolves couldn't revert to their human form in the series. William the First and most powerful werewolf actually teamed with Marcus the most powerful vampire in the second movie. I will give credit to the vampires in Rise of the Lycans though, the Death-dealers were awesome looking and are actually an idea of mine for a build.
