The antonyms for the phrase "more out-of-control" are "under control," "regulated," "managed," "governed," and "supervised." When something is under control, it means that it is being guided or directed, and it is not running wild. A person or situation that is properly regulated can be kept in check, which is not the case when it is out-of-control. To manage or govern is to take responsibility for an activity or group of people, which can help keep things in line. Supervision is a critical component of keeping something under control, as it ensures that there is an authority figure there to provide guidance and enforce rules.
