So many different types of object, so many different syntaxes. The tidyverse makes sense, and sure, is elegant, but if your colleagues are using base R. Don't even get me started on docs and Stackoverflow for R. I much, and always will prefer Python.
The one area I still go back to R is on proper survey work. I've looked for years and haven't found anything equivalent to the survey package for Python. I do like that R tends to start from the assumption that data is weighted.
Fortunately I don't do surveys much anymore.
