Well, you have to look all the differents between them.

Dawnguard

- Access to Crossbow: It's a very powerfull weapon if you get the enchanted version which can ignore 50% armor

- Pets: You'll have two dogs to follow you as a follower

- Creature ally: Armors Trolls will help you in combat if you hire them

- Spells against Vampires

- Access to Vampire Lord Form (After questline)

- Trainers: Restoration master, Smithing trainer, Heavy Armor master and a Archery master too.

Vampires

- Access to powerful rings: You'll can get two very good rings (Ring of Beast: +100 heath and +20 vampire claws damage / Ring of Erudite: +100 Magicka and enhance magicka regeneration)

- Access to two amulets: Two amulets can be caught to help you in Vampire Lord form.

- Access to Vampire Royal Armor: Isn't the best armor, but the 125% Magicka regeneration can be useful for you and come on, it's very badass (my opinion haha).

- Pets: 2 Death hound dogs can be use to help you as a follower.

- Spells heal and evoke undead creatures

- Creature: Can summon a gargoyle to help you in combats (Only available in Vampire lord form)

- Acess to Vampire Lord form

<p style="line-height:22px;">- Trainers: Two-Handed master and Speech trainer

<p style="line-height:22px;">- With Dawnguard DLC, when you are in vampirism stage four, you won't be attack by people anymore! It's very good, now you can travel and walk around as a normal person.

<p style="line-height:22px;">- You can use Auriel's Bow with Bloodcursed arrows to block the sun, doing this, the negative effects causing by vampirism won't be work! One more good point here!

<p style="line-height:22px;margin-bottom:0px!important;">You have to concern others factors too, this is just a little abstract about the theme. Serena can be a follower in both sides and you can turn in a Vampire Lord in both sides too, however, the rings, amulets and all the other stuff which i mentioned can't be obtained if you join in Dawnguard.
