I found the storyline to be very underwhelming, two petty sociopaths bickering over some old feud. It was probably the second best of Fallout 3's DLC after the Pitt, but that's not saying much.

I can't really tell what's the "best DLC" as I hate the whole concept to begin with. New Vegas DLC's felt that they tied together and told stories I felt were appropriate, so I guess I pick Dead Money for this poll as it offered, imo, the best balance for challenging gameplay and storytelling for what it offered.

I still think DLC is a waste of time and money, and that (proper) exapansions are where the real substance is for the player to spend money and enjoy the full worth of it.

Got to be Lonesome road. The marked men are tough fighters, theres a whole host of crazy weaponry, nuclear bombs lying around and thena climatic battle between you and the man fom your past, Ulysses.

The other packs are good but miss the personal edge. Additionally you get some cool gear toowhen you leave. Fun Fun Fun
