which DLC is best? (skyrim)

so i got enough extra money to buy 1 of the skyrim DLCs. since i have no experience whatsoever with any of them, i would like you all to tell me which is best. Ps: most of you are probably going to tell me to pick the one i want, but i just want a little variety.(its on ps3).I only know the names of them: dawngaurd,hearthfire,dragonborn. if you have ANY of them please recommend one and leave a reason why you like it.

I got the most out of Dragonborn. There are many interesting quests and other stuff to do in the added area, and some extra stuff in Skyrim as well.

Dawnguard didn't seem to have any replay value, and the added regions weren't very interesting. Fun if you've got extra cash.

Hearthfire I've never gotten anything out of, but I know others have.

I only have Dragonborn and Hearthfire, but I've heard enough about Dawnguard to know what's going on.

Between Dragonborn and Dawngaurd I have to pick Dragonborn. At least if you postpone doing that one all you have to worry about is every now and then not being able to collect dragon souls. Apparently if you get Dawnguard, vampires will attack a town every now and then. Wouldn't be much of a problem except they can and will kill NPCs, including plot and quest important ones.

Hearthfire is alright if you enjoy buying houses in the main game and wish you could design your place. Personal opinion is that the greenhouse addition is the most useful one if you're one for making your own potions. Combine that with the fish hatchery you can have at one of the three houses and you never want for plant and fish based potion ingredients again.
There's also that adopt a few orphan thing as well, but I haven't done it yet. Apparently you can get some items through them.

lol checked and already had dawngaurd loaded a few months ago. you make a point ill get hearthfire,since my assassin needs constant poisons i will get hearth fire. i will update you all when i begin to build my house its gonna be epic. enchanters tower and green house im set. got like 50,000 gold.
