The only other in the same league as VBox > is linux-kvm (6:7 between them). It's not entirely true that an OS has to have support for Xen to run under it. It's true for paravirtualized guests. However, if your hardware has VT-x support Xen can do full virtualization. It's not as fast as paravirtualization, but I'm successfully using it on one system to run an unmodified Windows XP installation as a guest OS. What's unique about VirtualBox is it can do full virtualization on old hardware that doesn't have VT-x support.
