Neither.

If you are really using Drupal's APIs properly, the amount of breakage  
is rather small.

Here's a poll node I made:

Here's the same poll node after turning off the poll module:

Not too bad. The only error I could find was from attempting to edit  
the poll.

If you are disabling modules on your site and not smart enough to go  
and delete or unpublish the content created, I don't know if that's  
something we should watch for. It's not inconceivable that a user  
could disable or un-install a module unintentionally, so I think core  
has already adopted the best approach here.
