I don't think it really matters that much. Both are solid platforms and either could be argued in favour of the other reasonably. Rather than spending time on both though as some have stated, I think you're much better off just flipping a coin and digging in head first, fully commited, and concentrating on the more important thing... your app design. One of the great things about full-stack frameworks like Rails and Django is that you don't have to agonize over all of the components, so why agonize over the framework itself? Just do it. Switch for your next webapp if you feel like it.
