I prefer male cats for the stated reasons, however there's enough swing in personalities between genders that it also depends heavily on the kitten and upbringing. I agree you are most often going to end up with a female in charge of the feline household with mixed genders.
I can't say for certain yet until I get my SV baby one week from today, but I know she's a super curious, loveable soul. I want cat-itude more than I want to keep all males and I knowingly want to disrupt the current state of the household, so it made getting a female the best choice, even if it wasn't obvious to me for a long time. Since I wanted an SV, I wanted a big F2 or F3 male but the more I thought about it, the more I realized that this would have to be a 4th cat in the future ~5 years out.
My alpha male Anubis is extremely playful and his brother doesn't like to wrestle at all, only chase. They are from the same BYB and different litters. He craves attention and is the people's cat, where as Ra is bonded strictly to me and everyone else is beneath him, tolerated and kept at a distance. Ra doesn't like Anubis being dominant but there's little he can do, he's 1~1.5lb lighter and an inch shorter in length. So when they wrestle, Ra is most always on the defensive.
Bringing an SV female who will take charge will provide an outlet for Anubis to play and allow Ra the peace and quiet, time with me, without making Anubis jealous. A win-win situation. It is very unlikely to go the other way where Anubis remains dominant, becomes the loner, and the SV takes to Ra more. We'll just have to see!
