AO globe life vs symmetry financial?

I had an interview with both companies. Both seemed about the same to me ('m new to life insurance). Both offered about the same pay and all. Only difference was AO you don't pay for leads, you call a list of people who've already "expressed interest" vs symmetry where you buy leads. With symmetry you can buy leads for as cheap as $0.50 all the way up to $60.00 for leads. What's the difference between the cheap leads and expensive leads? And do you work for either company, if so what has been your experience? I'm only looking to make this a part time job.
