Hmm... interesting. There are some options I like over robocopy from the command line perspective, and there are some options in robocopy that I would prefer over this one.
Lot more logging options in RichCopy over robocopy, and the ability to pre-parse the directory is nice along with being able to specify multiple source directories. Robocopy still has the ability to throttle copies over network using the Interpacket Gap delays and the ability to continually monitor a source and copy on changes based on time and/or # of file changes within the source.
