Comparing developers is like comparing apples to pears. The vagueness comes from the fact that software development is such a broad profession. It is a combination of many different factors, for example handling with databases is totally different than graphics. Of-course there are big differences between beginners and experienced software developers, but it becomes harder when you compare specializations. Furthermore, I do want to note that understanding user needs can greatly improve your effectiveness. Because not building something can save you multiple weeks or months of programming.
