R’s the best, bc it’s been a statistical analysis language from the beginning in 1974 (and was built and developed for the purpose of analysis / modeling). Also, the tidyverse is marvelous. It provides major productivity in organizing and augmenting the data. Then there’s ggplot, the undisputed best graphical visualization system + built-ins like barplot(), or plot().

But ultimately data analysis is going beyond Python and R into the realm of Stan and PyMC3, probabilistic programming languages. It’s because we want to do nested integrals and those software ecosystems provide the best way to do it (among other probabilistic programming languages). They allow us to understand complex situations and make good / valuable decisions.
