R really is/was the superior traditional data science language. Python ecosystem is slowly catching up though.

ggplot vs matplotlib

dplyr vs pandas

And I loved that everything in RStudio was so easily inspectable. Have a huge dataframe? Just look at it right in your IDE.

Altair and Positron should be just as good for your Polars @ Python needs. With software like Marimo notebooks and VegaFusion, Polars/Python experience starts beating R by quite a substantial margin.
