It's rather the opposite. Using querystring is the correct (intended) way, fragments are a hack. A fragment is a way to jump to a named anchor within the document, which by convention has been "misused" by developers to do client-side routing and URL state changes. This workaround was needed when history push state did not yet exist or work across browsers. The hash hack is no longer needed, but still popular. Does it matter at this point, for client-side state? I think real query strings "look better", which is subjective but a more real world advantage is as follow. When you start out with a fully client-side web app (server sends empty body/div only) and use proper query strings in the client, you then later have the flexibility to add better server side rendering without any URL migration needed. Because the server can read the querystring, unlike hashes.
