I think you should choose the one you think smells the best.
But, everyday I spray my hair before I leave for work with the TT RTM. At my job, there has been many lice cases. I even had head to head contact with someone I later found out to have active lice in her hair. I've never gotten lice. I believe it is from using the Tea Tree. I even keep 2oz bottles in my desk and purse, just in case.
