They each are better for different things.  As with many questions, the
answer depends quite heavily on your needs.  UMLs are quite independant,
for example multiple postgres instances can run because shared memory and
semaphores aren't shared, nor is process space.  UMLs however are pretty
heavy-weight.  Jails have issues, from what I've heard, with running
multiple postgres instances, so many fix that by running a shared postgres
that the virtual servers can share.

 The direct use of force is such a poor solution to any problem, it is
 generally employed only by small children and large nations.  -- D.  Friedman
