I'm deploying a simple SPA I wrote as a sole developer for a client later this week, and the clients have been thrilled with it so far. I've written less code than in other traditional webapps, the app is responsive and works well, and I know that sudden changes in server infrastructure (they're on-prem hosted and looking at moving to a Windows/IIS environment) aren't going to require a full-on rewrite. I think that's probably the sweet spot for SPAs though honestly - small scope internal apps (served over relatively quick intranet connections) with access to minimal client infrastructure (all you need is a web browser).
