Negligible differences in hardware between the two although the PS4 did the memory right. For me though it wasn't about hardware. Microsoft loves Windows and XBox is chock full of Windows based code. In my line of work I get paid to fix all the bug awful security flaws in Windows. Right now it is correcting the idiotic decision to make the login screen in 7 run under Superuser permissions. I flat out refuse to use any networked device that runs Windows code because I know for a fact how broken and insecure it is.
