It's not a Rails vs Django feature comparison that gives Rails the edge. Convergent evolution means they're pretty much on par with each other all the time.

The difference is in the size of the ecosystem as a whole. The Ruby web dev world appears to have more (or more visible) participants. Which affects things like Stack Overflow, web-specific packages on Github, blog posts, etc.

It's not an order-of-magnitude difference, as far as I can tell. But still significant.

It was particularly those web specific packages on github that I was curious about. For example, is there a package for doing CAPTCHAs for rails that's better than all of the ones for django? Better admin apps? Better apps to help you integrate with bootstrap more easily? Or create REST interfaces?

These things would make a huge difference to productivity if one platform had more (and better) of these things, but I haven't noticed that to be the case.

Stack overflow QAs covering virtually every possible problem you'll encounter.

I much prefer Python/Django, but when I get stuck, it always lasts longer.
