*As far as I am concerned xcopy is best for me.*
xcopy has a flaw in it (acknowledged by MS) that makes it unsuitable for use as a cloning program.
xxcopy (a free download) does not have that flaw, and so is a better solution - and no more hassle to use.
However - as a general point, I agree with much of what you say - in some cases, some of us may have tried variuos solutions, and come up with some reasons why we use a particular solution - these experiences are of course useful for those who haven't.
