Every time there is a topic about the 'strongest' technique, various skills can only be considered for different uses. For the purpose of a Utility stand-point, I believe The Strength of a Hundred Seal is at the height for any Medical Ninja to attain. The Seal itself grants the user three primary benefits; chakra, regeneration and the ability to conduct Katsuyu. As a Utility option, the user can channel their chakra and use Katsuyu to monitor and maintain a village-wide area. Katsuyu is able to heal moderate wounds and protect civilians from large-scale catastrophies. The user can also communicate telepathically with Katsuyu, collecting information both as a survey and search party.

The only draw back I can think of is that the user has to remain stationed, which could be fatal if they are unguarded.
