I also was deciding between which language to learn and its corresponding web framework. What's the criteria for you? For me, one of the main criteria's is the applicability of the language and its supporting ecosystem across many application domains (ie. web, scientific, systems programming, etc.). I am not tied to either language (not yet at least) so the decision was based more on "bang for the buck". I decided that Python is a better investment of my time. This was largely based on the fact that Python is used in many, many areas outside of web development. As a result, I feel python will server me more across most domains versus Ruby. It's true that Ruby can also be used in many different application domains but based on my research, it just doesn't have the legs that Python has for general programming. For better or worse, Ruby is widely known as "Ruby on Rails". In terms of which language is better, both are good so this wasn't a factor.
