The concept of Workspace is one of the biggest pros of scrivito.
As a developer, the Workspaces helps me a lot with testing new features. Change code, test in a working copy and delete it. No other person has to watch out.
Also a big plus is the headless design. It makes it easy to create webpages, apps or skills for Chatbots.
Now with the java script support, no administration of a web server is needed any more.
Built your website your way... not limited by your CMS, just add editability to your webdesign you want!
