From my experience Rails devs tend to care more about the quality of their work/impact of their changes on teammates, read dev blogs/books, go to meetups, care about testing/documentation, ways to source good candidates and working with good people.
Basically they just care more about doing good work. I must underscore though that my impressions are tempered by the fact that I primarily worked in enterprisey Windows-stack jobs, but that's also more typical - you're not going to find many modern startups going w/ .NET or Java. The tools themselves aren't really the problem, it's the implied culture.
Why is this? Probably because of the goals of each. .NET and Java were an outpouring of efforts from the 90s to harness issues of scale on enterprise systems. It's a pre vs. post information age phenomena, open source folks are going to be more of a hobbyist mindset.
