Recently, we really liked Rutile's White Day event! Our favorite writer is, well, "Undisclosed"--we're pretty sure Rutile White Day 24, Heathcliff Xmas 23, and Figaro's May 23 are all by the same Undisclosed writer. There's definitely other anonymous writers though, so it's a bit of guesswork.

For the entire lifespan of the game though... that's tough... I usually say North Rhapsody. Sen says, "this is a passion hobby," so you have to love it all.
