SwaggerHub is really easy to get started with, it's super intuitive and allows you to generate docs in a matter of minutes. It's also very cheap compared to other services. I don't have any issues with SwaggerHub but if there are any, they're probably not worth mentioning. If you want to be able to quickly create APIs and easily share them with your team, this is a great service. We were previously using SwaggerHub to create our API docs and we've been able to use them as a base to start building our own API docs.
