Should I take Prolia or Evenity with Xeljanz

I currently take Xeljanz, and I just recently had a mastectomy. I now have to go on Anastrozole for treatment to prevent cancer. This medication usually puts the person into osteoporosis and my doctor is considering either Prolia or Evenity. Both have serious side effects, and I would like opinions as well as if anyone taking either of these to tell me about their experiences.
