Haven't had much time to go over 5 different features but one I regularly use is the wipe/delete feature using the DOD algorithm (there are 3 options but I prefer the most efficient/effective.) I believe the FW features in Windows are non-existent in MAC if I recall correctly, or if there, not with the same UI and customization options.
If standardization between Windows and Mac is an issue, try using the Windows Subsystem for Linux with a distro (probably Debian would be best option unless the devs here are more familiar with OpenSuse) and the Github project Wsltty, which brings console features that are in Cygwin from the Mintty terminal to the console used for WSL. There is a bit of interop available for Windows/Linux and is greatly enhanced with the upcoming Spring Creator's Update in April, so that might help standardize what's available in Linux (which includes MAC) and Windows.
