...and Rails surpasses Django in other core areas... Not all problems are nails, hammer not tool for all circumstances, news at eleven.
Rails and Django are very, very similar in what they set out to accomplish, but they do so in different ways. TBH I don't really think you'd every come up against a project that was obviously suited to one framework or the other.
For example, I think Rails has better support for migrations than Django. Its not a huge, "game-changing" kind of difference, but its an instance of something that Rails surpasses Django in a core area. There are similar examples of Django being better.
I just think great-grandparent comment is a really lame analysis of technology. "This thing is better than other thing." Thanks for your deep analysis there sir!
