No doubt both solutions have merit, but Drupal requires an army of
developers in order to implement the solution. Remember, free
isn't always free and Acquia being a services organization knows

implementations costs are FAR lower than what you describe for a
mid-market or public sector customers.
Keep in mind Adobe is the leader in the WCM market for a reason.
Adobe is developing a Marketing Cloud and employs an army of dedicated
developers to building a unified platform far beyond that of Drupal.
