I have never used Superset, but it is an Apache project and doesn't come with support, and you will need to find a third-party company to help with any issues you have with it. If you are using this for a commercial project, I'd advise that you use Metabase since you can always reach out to their team to get support with it. For a personal project, I have used Metabase in the past and can attest to its great user experience.
