compiz or metacity+composite

I'm also a little lost. What really happens when you install compiz and
select the Desktop effects in the Advanced preferences? Is metacity
disabled? In this case, should the metacity package be uninstalled? On
the other hand, what's the difference with enabling the metacity
composite extension without installing compiz?

Cheers,
