Favorite Battle You've Encountered or Prompted?

Title is self explanatory. After deciding the local merchants needed the loot and gold more than the bank did, I just wrapped up a successful, glorious 50 minute bloodbath at the Counting House. This is my 4th playthrough, and the first time I've given that a shot; this was hands down my favorite battle that I've experienced in the game, and I was curious what big fights the rest of y'all have loved? Scripted events or extra curricular activities, what are some of y'all's most beloved beat downs?
