Ask HN: RoR or Django for GrubHub Style MVP?

I'm about to start building a simplified version of GrubHub. I'm completely new to coding and I'm trying to get an MVP online quickly. I'd slightly prefer to learn Python over Ruby, but I'm more concerned with getting my site up quickly. So my question is: would building a simplified GrubHub site be significantly faster using RoR compared with Django? Or would they both take about the same amount of time? Thanks!
