I guess Kogetsu is the most popular because it is the most balanced: since it lacks any specific flaws, such as Scorpion's low durability, the user does not need to compensate for them with other Triggers or training. Overall, it is probably the offensive Trigger that can be wielded more easily by the largest number of people. For the same reason Tamakoma's Triggers are unique: because only a few agents would be able to fight well with them.
