Which is better for what? Robocopy vs xcopy vs copy

ive been using robocopy to backup my files i was just wondering what situations were better for which tool?

I prefer robocopy too.

I only use copy when I need to copy robocopy to system32... And I haven't used xcopy for months now.

whats robocopy? i use xcopy religiously

(i do know how to use google, just figured Id get a better answer from you guys...)

Robocopy is at http://www.ss64.com/nt/robocopyXP.html not too bad, I use xcopy becuase it has the network restartable and verify. Excellent to make sure that all is ok. also will copy hidden and system files directly, and can copy all the ownership settings in ntfs.
