Sims 4 - Favorite expansion pack?

I have played the Sims games since the first one. I still love playing this game even today. I sometimes go back and play the first one just to laugh at it. Anyways, for those of you who play the Sims 4, which has been your favorite Expansion pack? We have another one coming out in a few days. I thought it was a good time to ask.

For me, I have to say the Cats and Dogs expansion takes the cake. I got the Sims 4 alongside it and have never played it base game only.
