The short version
Duplicator packages a site into an archive plus an installer script that you run on the destination server. It is powerful and popular with developers who like control over the process. Quick Restore keeps the whole flow inside WordPress: upload the file on the new site and click restore.
When Duplicator is the better choice
You are comfortable uploading files by FTP and running an installer, or you need to deploy to a server with no WordPress installed yet.
When Quick Restore is the better choice
You or your clients want a restore that happens in the WordPress dashboard, on shared hosting, without FTP — and a one-time price.
