Just gonna chime in and say the same thing as many already said-- I have both, and Werewolves is a much better pack.
I use the build/buy and CAS constantly and have played 2 werewolf sims so far. They are very well-developed, lots of fun, can be played in very many different ways depending on pack, perks and temperaments. Also, not buggy.
Both packs come with interesting premades and beautiful worlds with a small number of lots. Moonwood Mill has a lot more gameplay going on in the neighborhood terrain areas.
I would say My Wedding Stories is best either for people who really want to throw big complicated weddings often, or people who really love the Mediterranean world of Tartosa.
