BEST event ever.

I voted for Whacking Day; it was my very first event in the game and it's still my favorite. I had just started playing, had next to no friends in-game, and I still managed to finish with every price! I was tapping like a madwoman though, I remember my boyfriend being mad because I was tapping in bed in the middle of the night and waking him up... I'd love to have a second go at it now with more experience and a full neighbours list.

Stonecutters is a close second, I really liked the daily riddle and the mechanics of that event were just generally well thought out; I also really like the Halloween events, 2013 being my favorite of the two I've been around for.
