Shadowrun: Hong Kong - Most used/useful etiquette

In Shadowrun-Returns, there are many etiquette that will allow you to answer or to say something during the dialogue that can save your life, give extra XP or easily solve some puzzles.
Sometimes, a specific etiquette is not even present in the entire story, so it is a waste of Karma points. Other etiquette are constantly showing up.
Does anyone know what etiquette is the most useful for the Hong Kong release of the Shadowrun-Returns?

So far, Academic and Shadowrunner already appeared 2 times each and I just started working for Kindly Cheng.

Gang, Shadowrunner, Academic and Security
