As someone with +20 years in finance (hedge funds/trading) and knows .Net, Java, Python, C++, shell, etc, the first question I'd ask is: where's the data?
If I'm being asked to do data analysis, it's because we need the answer yesterday. So, the tool I choose always going to be a matter of which gets me the answer fastest and with the least amount of friction. That's almost always dictated by where the data is _now_. Not where it'd ideally be.
