Femara or clomid?

Saw my gyno who suggested to start 2.5 mg Femara sicne I have pco. I still ovulate on my own tho with regular cycles

A fertility doctor at a fertility clinic today said he would prefer clomid as he has seen higher results from that.

What's your experience if any?

Husband has normal sperm count just been ttc for 15 months with nothing close to a pregnancy.
