I recommend Django because it's much more widely used. You'll find more write-ups, Stack Overflow questions, podcasts and conference videos. Instagram uses it. Disqus uses it. There's just a ton of help out there for a new developer.

While I agree that a lot of what Django does seems like "magic", getting to know how that magic works as you get more intimate with the framework will make you a better developer in the long run - so you can start writing your own magic.
