My experience with the cobs is that it gets wetter than a briar pipe. The cob has to be left to dry longer than a briar pipe. While the briar pipe, for me, is easier to smoke several times, because the moisture does not penetrate as easily as it penetrates a corn pipe. In the end, in a corn pipe, a dry or very dry tobacco is more suitable. It is true that the smokes are juicier and fresher, the tobacco tastes more real, cleaner. But it is also early because the only briar pipe I have, is very new and does not have a thin layer of cake, and at the moment it gives me a bitter taste, since the walls barely have some cake. That is my experience of smoking a corn pipe. In short, corn pipe let it dry as much as possible and add a dry or very dry tobacco. I still have a long way to go before I can know how to smoke a briar pipe, its aroma, its taste etc. The cleaning advantage is better in a briar pipe, you can wash it with water, not a corn pipe, because its walls absorb the humidity very easily. So I only clean corn pipes with 96º alcohol. This is my humble opinion. I hope it helps you.
