Apocalypse World: Burned Over

I've run and played a lot of Apocalypse World, but have only recently read the Burned Over hackbook. Is there anything I should keep in mind when running this "new edition?" It seems pretty straightforward to me.

I'm also curious to read about which gamechangers people elected to use (and how they played out in the end), which new playbook is your favorite, and whether you prefer standard 2E or Burned Over.
