FastRWeb is server-independent, easier to deploy on machines you have limited rights (i.e., you don't need to compile against apache or edit its configuration) and cleaner to debug because the client layer is so thin (the front-end doesn't die if R crashes). Also since Rserve is the back-end you can use its features such as updating data in the instance (control commands) or connect into the live instance from R itself to work interactively. Also you can technically separate web server and R server machines if you want to (or do load balancing etc.). It is also a little more than just infrastructure, e.g. it does query parsing for you and takes care of things like graphics etc. Clearly, that is something you can do equally well do with a layer on top RApache, so that's not a technical issue. That said, I don't know RApache well enough to provide a comprehensive comparison, because I don't have control over the machines that my stuff will be deployed on, so RApache is not an option for my particular use.
