Alternatives to Rstudio for an R development IDE?

I love Rstudio, Especially the new release. But I was wondering what other developer environments people here use. I've come across emacs + ESS, Visual Studio, and more lightweight editors like Atom/VS Code with a bunch of extensions added in. What setup do you all use?
