My takeaway from having worked on both traditional webapps, and SPAs (2 with homegrown frameworks built on backbone.js, and 1 with ember.js): SPAs, being more complex, demand a higher standard of coding and code review to not have eisenbugs. I have seen a lot of effort wasted on making SPAs work, when the customer would have been happier to have a more reliable traditional webapp. In one of these companies, SPA architecture was chosen because the backend was unacceptably slow. Instead of fixing that problem, we adopted more complexity by transitioning to SPA. When I left, the backend was still slow, and the SPA was breaking all the time. It felt like a waste of effort and I would never do an SPA by choice again.
