which is better triplus or rapidus?

[Pesh]

Your base Level of Treasure Hunter is determined by your Base TH, Plus Gear. For instance:

A Player with Treasure Hunter II, when Striking a mob, Would inflict "Treasure Hunter Lv. 2" on the Enemy. Upon which each upgrade would increase it by 1.

A Player with TH2 trait, Thief's Knife, and Assassin Armlets would inflict "Treasure Hunter Lv 4" on the Enemy, and so on.

True, but the first time you see the message, you will always see your TH level +1. As a TH6, my first message is always a level 7 effect.
