Each of them have their own quirks, and often depends on the day. Mathey/Rocky usually has the most options and most often has ethnic foods, which are pretty hit or miss. Whitman usually has one main entrée that can be either really good or really not. Butler/Wilson is consistently average, but occasionally features a really good entrée (and has the most extensive vegan bar out of any dining hall). The CJL (Center for Jewish Life) has very good vegetarian options, and a few times a week will have a stir fry bar that is probably my favorite thing to eat on campus. Forbes, known for its Sunday brunch, has consistently the best food, but it is also the least convenient to get to from main campus.
