Hi Neil,
I’d suggest having a read over this recent thread here on the forums, Are We in a Scripting-dependency Backlash?, as there was a lot of discussion on the pros and cons of client-side rendering and progressive enhancement.
Basically, considering the kind of site you’re talking about, I’d definitely stick with server-side rendering. Using something like AngularJS would make the site inaccessible for anyone who doesn’t have JS enabled for whatever reason (older/non-standard browser, company firewall problems, etc.). By all means use JS to enhance the site and add nicer functionality, but the site should still be usable for those without it (IMO).
