For what it's worth, I think GNU Octave could put up a good fight here as well. I'd be interested in seeing it included in the comparison, though (I'm afraid it would lose on multiple points if only due to lack of funding, but it is very usable). I currently have a fairly big project written in Octave, but will likely rewrite it in python for maintainability (and would rewrite it again in something else if it grew too much for Python). there's also Sage, which is an interesting contender, but I do not know enough about it to know how it compares. Arguably, though, Sage and Octave are more geared towards numerical computing than data science, and I think that's where they shine. So, depending on your data and the processing you need, those could be more adequate.
