Is Orilissa (Elagolix) better/worse than Dienogest?

For context: I got diagnosed with endo in October via ultrasound (they found it because one ovary was stuck to my uterus and I had some chocolate cysts on both ovaries) and I was put on Dienogest 2mg, I've been taking it for about two months now.

Apart from some mood swings and spotting at first, it's been great, Dienogest is a godsend. No periods, no pain, I've been cruising. Skin's been very clear too.

I went back for a checkup yesterday though, and they found that my cysts are still there and haven't really reduced in size. My ovary is also still stuck to my uterus. Hence, my gyno is saying she might switch me to Elagolix in a month or so. I'd like to know y'all's experiences with Elagolix— have any of you taken it after being on Dienogest? How do they compare?

I'm scared to switch since Dienogest works so well for me pain-wise, I don't want any scary side-effects. Any info would be very helpful <3
