I guess the other thing that you’re leaving out is the number of users your site will receive. For smaller numbers in a simpler market you can get away with more technically complex solutions. My last four years have been spent working on data driven platforms with a minimum of a billion individual visits a year, and for those typically prerendering the common parts and pushing them to a caching layer is much more computationally efficient and leads to a faster client.

If you’re dealing with a lot of custom data for each user they that plays less well into the prerender solutions. But again, it comes down to how best to serve your users’ needs.
