Should I find a class b driving job or work with UPS?

I am 19 years old and I just got my cdl class b licence and I was wandering if companies would hire me at my age with no experience? If not, then should I work for UPS as a package handler part time. Because I do have an interview set up with them next week. I know that ups package handlers dont make that much as people with class b trucking jobs. So should I go looking for class b trucking jobs and forget about the interview with ups or the opposite?
