Yea I would say that is one of the biggest things that made me decide to switch there. WordPress does allow for a good amount of features and tweaks, but I think in the long run manual edits of hard-written php pages is something to be avoided.
For example to configure WordPress to work with multiple domains it requires a weird wp-config.php edit, and for the mod mentioned above it also requires some manual editing.
For the installation of Drupal I have there was no file editing at all done. In fact the way it is set up I can run multiple domains/subdomains all from the same installation and root directory.
Also adding just about anything you can think of to a page, article or whatever is a lot easier with a standard CMS platform.
As far as plugins, I may have gone a little crazy....
