What makes Richcopy really stand out is not the GUI or the sheer number of options available, but its support for multithreaded copying. Multithreaded support means faster copying, as files can be copied in parallell instead of just one at a time.
Multithreaded File Copies with Robocopy in Windows 7
Robocopy is included in Windows 7 and features a new multi-threaded copy option. To perform a multi-threaded copy, you use the new /MT[:n] switch, where n indicates the number of threads to be used. By default, n is 8 when you use the /MT option, and can be any value from 1 to 128.
Note that the multi-threaded option is not compatible with the /IPG and /EFSRAW options.
