Dawnguard - not particularly. Unless you really love vampires. I thought it was a little empty and lacking in depth.
Hearthfire - Just adds the ability to adopt kids and build a house. Bit of fun, if you like The Sims.
Dragonborn - The best one in my opinion. Loads of new areas and side quests. Feels like a genuine add on.
Are you on PC? If so, get on to here or Steam and get some free mods. They can add all kinds of stuff, from nude Lydia (come on, we all want it) to new guilds. There's a good survival mod that adds hunger/thirst and your character getting affected by adverse weather - so no more running up a mountain in a loincloth.
Just on PS3 mate which is why I forgot about the DLC as it took about 6 months longer to cme out than on pc and xbox.
I have a decent desktop now, an iMac, so will transfer some game sonto that from now on.
