deciding UFS vs ZFS

We have two 'big' filesystems, UFS and ZFS. How do people decide when
to use which? I'm trying to build a "decision matrix" of when to use

My virtualization system runs KVM, so I use UFS on VMs. Restoring
ZFS disk images via dd can be problematic.

For larger boxes running on real iron, I use ZFS.

But there's a whole range of conditions between these two. And the way
to fill in the gray spaces is to ask.

So, how do you decide to use which filesystem?
