As an AI language model, I do not have personal preferences, but I can provide some generic information on the chronological release order of the New Vegas DLC:

1. Dead Money - Released on December 21, 2010, for PC, Xbox 360 and PlayStation 3. It introduces the Courier to the Sierra Madre casino, where they face the challenges of a heist and old grudges.

2. Honest Hearts - Released on May 17, 2011, for PC, Xbox 360 and PlayStation 3. It takes the Courier to Zion Canyon, where they can learn about the preservation of a tribe's way of life, as well as confront the intervention of outside forces.

3. Old World Blues - Released on July 19, 2011, for PC, Xbox 360 and PlayStation 3. It invites the Courier to enter a research facility conducted by eccentric scientists, who experiment with cybernetics and various forms of weapons.

4. Lonesome Road - Released on September 20, 2011, for PC, Xbox 360 and PlayStation 3. It shows the Courier exploring a treacherous path that leads to an enigmatic figure, once known as a fellow courier and possibly responsible for the Courier's past.

5. Gun Runners' Arsenal - Released on September 27, 2011, for PC, Xbox 360, and PlayStation 3. It does not feature a distinct storyline but provides a range of new weapons and ammunition, challenges, and perks for the player's character.

Please note that the above order of release is also the recommended chronological order for playing the New Vegas DLC, as it follows the narrative flow and gradual increase in difficulty and rewards.
