I am about to embark on a project which will be a database with potentially thousands of entries. It is for an Australian audience so load should not be particularly high. The developer who is interested has a strong preference for RoR. However I am unconvinced of the benefits of RoR for all aspects of a project.
For example, while RoR seems faster to write, it seems to take more time in terms of server maintenence. Also in terms of potential for others to take over the project in the future, there seems to be fewer RoR developers compared with PHP. So I guess I'm concerned that while RoR might seem faster up front, that over the longer term, PHP might be more efficent in terms of stability, maintenence and potential recruits.
I know from experience that developers tend to be passionate about such comparisons and this is a concern for me as I want the decision to be based on objective measured criteria rather than subjective personal opinions. I'm not trying to offend anyone in either camp, just wondering if my personal observations are valid?
