The Alpha/Beta/Omega thing is nonsense, in my opinion. Humans are far more complex than that. I'm female, and I can say that while yes, I'm more interested in a guy willing to stand up for himself and those he cares about than one who hides in the bathroom and cries, I am absolutely not interested in the sort of guy who always takes charge. I like relationships where the guy treats me as an equal, you know? I don't like and never have liked jocks or other pushy guys.
Actually, in my opinion, girls who are looking for that kind of guy have probably been emotionally hurt in the past, which is why they're looking for someone to take charge of them emotionally. Unfortunately, this is not a good way to live or a healthy way to build a relationship, which is why people get stuck in a cycle of abusive relationships. And... let's be honest, a lot of those so-called "Alpha" guys do end up being abusive. If you have a relationship where one person is always in charge and the other is always just meekly following behind, it is pretty much guaranteed to end up abusive. Maybe not physically, but emotionally. And that's why I am much more interested in "Beta" guys (if there is such a thing, which I don't believe at all) who actually care about me as a person than "Alpha" guys who only care about themselves.
I will say, though, if you're just going to be a wimp and let the woman in the relationship always take charge, you're not any better than the Alpha types. Grow up. And the same to wimpy girls, too.
However, I'm not a supermodel, so therefore my opinion on the matter obviously doesn't count.
