I got excited at first for hearthfire, it was the first DLC I ordered too. But, it got old fast. I still use it, I don't even build, just buy the land then go into the creation kit and build something myself. As to the other DLC's, I think Dawnguard is the best. Dragonborn was 'ok' but I was actually really disappoined in Solstheim. I get that it's an ash covered wasteland, sitting in the shadow of Red Mountain, but still. I just couldn't care about any of the people there, or make a connection with any of the new NPC's. However, Dawnguard had some really beautiful new landscapes, some very interesting new NPC's, and really cool looking armor sets no matter which side you choose. Plus, I mean, crossbows. So there's that. For me, Dawnguard ftw.
