How would you explain the difference between Nagatoro and Takagi San?

So I ask because I just started reading Teasing Master Takagi San a while ago as while I am up to the first volume, it suddenly got me wondering how one would explain what makes it stand out from Nagatoro as they both use teasing as a concept, and I was wondering how someone would explain the difference between the two manga series if they had to do a sort of essay on the subject.
