It also depends on the nature of the app. The SPA arguments often have two groups on each side. On one hand there are people building content-heavy sites claiming traditional Django/Rails stuff is perfect. On the other hand you have people who work on heavy web apps where the user is interacting with the application for many hours. These are more like desktop apps that happen to run in a browser. To provide a good modern experience for a heavy web app using traditional Django/Rails stuff is basically impossible. People will eventually end up creating a half-SPA half-Django monster. SPAs used to be harder to do 5 years ago. Now they are still not super easy but easy enough that you can more safely pick a SPA for many apps.
