I've been a Ruby (not rails) developer for 10 years and use python when hacking together hardware projects.
Generally speaking Ruby has a better standard library, the major libraries (gems) seem to be better built with nicer APIs and unit tests.
I think the best example of Ruby at it's best is the Sinatra web framework.
Having said of this, I don't think that Ruby is the language of the future.
In my humble opinion the language combination of the future is going to be Python as my interpreted language of choice + Swift* (for when I want a more strongly typed / functional language or when I need things to be fast).
* Swift could be my only language if they had an interpreter.
