What is the difference between drupal/recommended-project and drupal-composer/drupal-project?

The Drupal docs say to use composer create-project drupal/recommended-project my-project.

It also mentions drupal-composer/drupal-project, which was the recommended project starter before one was added to core.

Is there any reason to still use drupal-composer/drupal-project?

One difference is that drupal-composer/drupal-project uses a ScriptHandler class:

"scripts": {
    "pre-install-cmd": [
        "DrupalProject\\composer\\ScriptHandler::checkComposerVersion"
    ],
    "post-install-cmd": [
        "DrupalProject\\composer\\ScriptHandler::createRequiredFiles"
    ],
    "pre-update-cmd": [
        "DrupalProject\\composer\\ScriptHandler::checkComposerVersion"
    ],
    "post-update-cmd": [
        "DrupalProject\\composer\\ScriptHandler::createRequiredFiles"
    ]
}
