This is my ranking order
Because normal vampires have the advantages of the Necromage glitch and resistance to disease, poison, and frost. Werewolf is the better beast form in my opinion because they get a large bonus to health, stamina, and sprinting speed, and VL form is more of a hassle than help to me.
Most of the time though, I just pick neither and stay pure.
Yes, in fact both the vampires and werewolves are portrayed a bit shallow. One should be able to play mainly as werewolf or a vampire not just use the form when he's in trouble. To become a wolf and be able to hunt the prey not always go in blood frenzy... Interestingly there seems to be no such conflict in TES (at least it's not that pronounced). The only mention of the tension is the Harkon talking about "purging the filth" out of you if you're a werewolf.
Personally I find Werewolves more fun to play in Skyrim because of their mechanics. They have the positives of being able to transform into beasts with increased strength, health, and stamina. Given this and their increased movement speed they have plenty of advantages in combat over their enemies IF they choose to even utilize the power. Yes, over time vampires can become more powerful in the category of have an arsenal of vampiric powers to change the way a battle ends. However, this takes some time and leveling to obtain some of the more powerful abilities whereas werewolves simply grow stronger than they already are.
Also, completely not related to the argument where's a vampire mod like this one for you vampires? (WHERE IS YOUR DIVINES NOW?!)
OK, let's see two situations. You know you are hunted by a vampire or a werewolf. Would you be more scared if you see a werewolf rushing through bushes towards you? Or when you hear noises, glowing eyes in the darkness that disappear the next moment, biding the time till you get in his paws yourself? I'd certainly be more scared of a vampire
