Drupal has installation profiles and they are amazing time savers. For some of the most popular profiles, it seems like the plugins are chosen based on what Drupal developers use most, which are generally the ones that work the best. Each profile is created for a different purpose, so only the best plugins for each purpose are included. If someone wants to use the profile and does not like all of the options, they can modify it to fit their own needs. It would be really awesome to have some of these for WordPress.
