Or the fps filter.
This filter and the r option have different algorithms that have
advantages (and disadvantages) in different situations.
Are the differences explained somewhere in the documentation?
Not to my knowledge, them main difference is that the filter is
more greedy.

Sorry Carl Eugen - you are right. I did a test, and when I apply the fps
filter after setpts it not duplicate any frames.
Sure?
I mean: It may or may not duplicate frames but contrary to "-r"
the console output will not tell you.
As Moritz wrote: If your input is cfr, you only need setpts,
For vsync cfr, ffmpeg will still duplicate and/or drop frames based on
the framerate obtained from the filter buffersink. So fps or -r is
needed to modify that.
