I prefer Rmarkdown to ReporteRs because of its capability to convert one format to the other formats such as html and latex-pdf.
However pandoc (i.e. Rmarkdown)’s support for docx is not so great, so I had to use ReporteRs sometimes and it was a pain when I first used it.
Now I get used to it and I should admit that it is actually a pretty powerful tool for reproducible generation of docx documents.
