The two genders can have different traits with certain other species, but with rabbits I'm pretty sure both genders are the same e.g. personality wise. I've had many males and females and haven't noticed any difference. It just depends on the individual rabbit. If you've encountered aggressive or unfriendly female rabbits that was down to their individual personalities, not their gender.
I also agree with what Bunny Magics said. Females are just as special as males (no matter what species) and even females (or males) that are aggressive or unfriendly aren't being that way on purpose. They're just scared or shy or hormonal and will come around with time and patience (and spaying) like Bunny Magics said
I do understand if you want tame baby rabbits from the get go though. I just don't agree that females are nasty, or that any animal is nasty really. That's a superficial way of looking at it. Animals are more complex than that and can't be treated like damaged goods when they don't turn out the way we maybe would've wanted them to. They have to be met with love and understanding. Not that I'm suggesting you wouldn't, just that I know a lot of people do consider an animal that's not perfect to be like damaged goods and don't treat it the way it should be treated. Not usually out of cruelness, I think people just don't understand why the animal is behaving a certain way and maybe don't put in the effort to understand.
