Although this article is focusing on dplyr which provides an uniform API over various data sources, I guess the choice depends more on the personal taste: Do you like staying on R / Python or on SQL?
If you prefer SQL, using raw Arrow or in-memory data doesn't make sense - Except duckdb does support SQL queries over these non-db data sources as well.
Anyway, R data ecosystem very rich for both R and SQL fans and I as a Python user feel a bit envious.
