I assume that both the positions are in same domain. The QC inspector deals more with the quality and control of the process. In case of the technician, the person is going to be more on the process. So you have choice to choose either one depending on how much comfortable you are. You have to also check how much salary revisions are likely to happen. This way you can decide how to go through the hierarchy. I suggest you to talk with the people in this field and decide what course of action goes good for you.
