R is great if all you do involves working in RStudio and that is where it stops. The R runtime is painful to scale. You’re not going to do anything like FastAPI + scikit learn model serving. All the tooling is years behind what’s available in the Python ecosystem. I can’t speak for RStudio and their commercial offering since I’ve never used it, nor want to be locked into some vendor like that.

I’m going to be honest, even RStudio sucks compared to PyCharm. Like really sucks. I almost believe people who love RStudio have never used a better IDE or don’t have serious software development backgrounds to know that it sucks.
