Initial page load feels faster when rendered on the server. The very moment you navigate to another part of the site, client-side rendering is a huge win for apparent load times. Not only can you give the user feedback that something's loading, but you only need to retrieve the delta from the server between the page you're on now and the one you're going to. Within a few clicks, the amortized cost of the SPA in terms of both latency and over-the-wire size is already lower.
