The main benefit of an ESD license is unquestionably its price which, depending on the case.
A retail or Windows license of Office is a type of license that allows you to install Windows and/or Office on any PC, allowing in case of need to be moved from one computer to another. In other words, if you decide to change computers, you can easily take the version of Windows and/or Office and install it on the new computer without incurring any kind of problem. But this does not mean that you can install the same version of Windows and/or Office simultaneously on multiple computers, but only that, once you uninstall Windows and/or Office from the old PC, that same license can then be used on any other computer without meeting any problem.
OEM version is a type of license that is inextricably linked to a single PC. In practice this means that if for one reason or another you no longer want to use that PC, then you will no longer be able to use the same Windows and/or Office Product Key on the new computer. Also, if you want to change some components on the PC with a Windows OEM license, probably that same license then can not be used even on the same computer.
