There is a fork for typescript  that I just started using for a project. So far so good. It is easy to use and seems to work just as well as create-react-app.
To be honest, though, I don't know that I am truly exercising all the features of create-react-app. I just used it to get started, and to build and run. Everything else I do through npm / yarn (add new components, mainly). Haven't ran into an issue yet where I can't do something I want to do. Early days of the project, though.
