Calibre is a powerhouse of an application. It is built for people that want really in-depth metadata curtailing and exploration. Kavita is not that. At the moment, in terms of metadata Kavita is pretty limited. The current release is adding more metadata support (local) and attempting at downloading metadata from external sources (nothing else really does this except other tools). It really depends on you and your library. I personally just want to be able to read my stuff and focus on things like genres and put collections and read lists together (for custom read orders), so Kavita is the best solution. If you want in-depth metadata, then you're better off setting up Calibre-web or Komga.
