Actually, this really had to do with how VNC only sends mouse positions
as relative, so early versions of a lot of these solutions had very
funny mouse issues. Eventually they all managed work arrounds to figure
out where your mouse really was.

To be fair, all of the approaches require kernel modules. The kvm ones
are open source and upstream, the others aren't. Because they all use
kernel modules to assist various parts of virtualization, they are
typically mutually exclusive on a single box. The fact that kvm is
tested as part of the distro, helps eliminate bugs.
Virtual Box has some nice usb pass through support, which is still
lacking in KVM. Their interface is still slicker than virt manager. If
you are using virtualization because you need a windows guest to talk to
devices, it might be a better choice.
Personally, I've got Virtual Box on my laptop, because I needed a
windows guest to talk via usb. KVM is what I run on anything but my
laptop for guests (linux or windows).

There is no silver bullet. Plus, werewolves make better neighbors
