While it makes sense to prefer the for hook_form_FORM_ID_alter(), it is called
before the more
general hook_form_alter() so if you want to run after all other alterations you
need to use hook_form_alter() .
Also since CCK uses hook_form_alter(), if you want to run after it you need to
use hook_form_alter().

Exactly. Knowing how to use the hook_form_alter hooks properly makes
customizing Drupal much easier.
Each time a form is built, it gets sent through every hook_form_alter
implementation in every active Drupal Module. And, as FGM pointed it,
it also goes through a specific hook: hook_form_FORM_ID_alter. Have a
look at both of these and play around with them. I personally prefer
to use the second one, because it's more specific and obvious what it
does, and you don't get one of those huge if/switch statements in the
hook... but sometimes you need to use hook_form_alter because your
changes apply across a couple of related forms, especially the node
forms.
