Some advantages of the Cauldron of Broth is you can get it quicker research-wise, and in some cases you need to use them.

In cases where your commanders are leading large armies, the Cauldron of Broth can become crucial to prevent starvation.

Which is why you use scouts with your winebags, as you are wasting a large number of nature gems if you use cauldrons.
