Hindi ako personally nakapag-take ng contraceptive pills kaya honestly, better to ask your OB-GYN about which one suits your body better, basta both are trusted brands talaga, pero different formulations sila so depende sa hormones mo. A few of my mum friends tried both at nag-switch lang based sa side effects nila, like one got worse acne with Yasmin pero okay lang sa Diane, so it's really individual! Your doctor can check your medical history and recommend which is safer for you specifically, especially if may existing health concerns ka.
