I'm an old R user forced to mostly use python because that's what the team uses.

R is so much better than python in many areas concerning data pipelines: connecting with external database systems through an unified API, superior data munging utilities, as well as plotting, a more comprehensive (obviously) statistical analysis toolset.

I even find rmarkdown vastly superior to jupyter.

But IMO the best reason to use R rather tha python is that its tools will make you approach the problem as a statistician rather than a programmer.
