User blog comment:Thewikilover/Dawnguard or Vampire? Which side has more benefits?/@comment-5229167-20120714215930

Dawnguard easily has more benefits. You can get all of the armor and unique weaponry from the vampires side by simply killing them, but if you join Harkon, you lose the crossbow schematics you are tasked to find, so wave goodbye to a dwarven crossbow or exploding bolts, etc..

Not to mention the armor. None of them wear the helmets, so if you think you're gonna be a Vorkan and just kill and loot all of the armor, you're wrong.
