Switching to jQuery made life so much easier. Once a feature is completed, I feel happy. With RJS, I was just glad that it was over. And, no, I do not want to touch it again :-)
I can say is that with jQuery you just get the JSON or HTML you need. And then you either process it or put it where its supposed to go. The server just creates the JSON or HTML.
An RJS file is a template for generating javascript on the server side with your data. Writing code with a tempting language is more of a pain than just writing that processes JSON or moves HTML.
