Agree with a lot of the people posting here, Founder's makes some awesome stouts, if you can find their Kentucky Breakfast stout buy it, it's really good but extremely hard to get (it's already gone from this year).
Bell's has some good stouts as well, kalamazoo stout is good as well as their pricier ones like expedition or java stout. I also like the poet from new holland, it's a good oatmeal stout. Hoppin' frog makes a lot of good stouts but they're pretty pricey (worth it once in a while imo). The best stouts I've had are really hard to find but worth it, Parabola from Firestone Walker and Bourbon County Stout from Goose Island are amazing, both are barrel aged imperial stouts and are really smooth with a ton of flavor.
