In my opinion based on few specific measurements both are best and great for developing web application. But learning Django could add more benefits on achieving some awesome skills i.e data scrapping, working with big data, geocoding etc. Although, you can do some of these with RoR but o found Python-Django is best for these task!

Both framework has excellent extensions (RoR-gems/Django-modules) but Django has lots of exciting modules which helps to achieve project goals with less headache.

Also, if we consider programming language for scientific research then Python comes first! So, learning path Python->Django could give you more career opportunity I.e developing web application, working on data science, machine learning etc.
