This is really subjective.
The thing is, I really think there's a push by many girls to get rid of every even slightly masculine feature, no matter how attractive it looks or works in toto. Many very attractive cisgirls have certain manly features like strong jaws or prominent brow bossing, and they have no problems finding work as actresses or models.
Unfortunately I don't looklike my avatar yet(Gina Carano) but I could easily pass for her brother now. She's about my frame size, build and height, and has a strong jaw. And despite that she's very smexy.
An overdone face IMO sometimes doesn't work because it doesn't match the body. Fact is, a girl 5'10"-6' with the neonotonous face of a preteen doesn't look right. Bigger girls have bigger features, and sometimes the most striking and attractive feature is a more androgenized one.
Regarding foreheads, DiMaggio seems to be the best currently. He does full type 3 reconstruction, while most others stick with type 1 shaving or type 2 shave/fill.
For me it depends on my sinus. I remember having a very thick sinus wall from my youth where I needed X-rays due to issues, so I may be lucky enough to take type 1 successfully. I've seen Mayer's results in person and they're amazing. So what if I still have some slight bossing? Go out in the world and look at the cisgirls with the same or more that not only look natural but sometimes even hot!.
I've always thought Z is a little overdone and cookie cutter at times, but there's some girls that are perfect for his technique. This isn't something where there is one perfect ffs surgeon and a bunch of lessors, this is something where there are a bunch of very good ones with different techniques and strengths, and the best one for one girl may not be the best or another.
