Do you have actual experience with developers of similar skill levels building a similar app in Spring and Rails?

While undoubtedly less expressive I think most of the bad rep Spring gets is because it's used in "Enterprise", which means programmers that are, if not of lower level, constantly interrupted and yanked around and told what not to do.

I wouldn't choose Spring anymore because there are better alternatives, but I'm pretty sure the 10x is in the programmer and not the framework. The framework might be 2x, if that, but not much more I think.

P.S. If you include Spring Roo then I'm pretty sure the 10x no longer holds, but I never got up to speed on Roo myself so I can't say anything authoritative on that.

Not rails. I've never used rails in a serious production application.
