React Storybook vs Chromatic

Earlier today, I was looking through the Meteor guide and saw that it suggested using Chromatic to do UI testing in your React/Meteor app. This is the first I had heard of this, but the guide says that it’s similar to React Storybook. Has anyone used both? I’m curious to learn more about the differences between the two.

Chromatic is the one we use internally, but react storybook is far more popular in the community.
