Which is a better IDE for R, RStudio or R Tools for Visual Studio

The Microsoft released the public preview of R Tools for Visual Studio a couple of days ago, and via their introduction video I got a bit sense of what Microsoft equivalent of RStudio looked like. To be frank, I personally prefer the user interface of RTVS which is more intuitive and kind of consistent with respect to its design language. But I have little idea how its functionality compares against that of RStudio. Any thoughts? omegle

The most recent release from MS I see for R Tools for Visual Studio is a little out of date, and not compatible with VS 2019. Can you point to the new preview?
