I have 6 boys and 3 girls. I love all cats, but prefer males (except for the spraying thing!). I think they're more affectionate, in my vast experience!
My males are big sweethearts (as I'm typing this, Willi is watching, from in front of the keyboard). Three of the males are Maine Coons; 2 are love-bugs; 1 is still semi-feral (their brother), and is FINALLY kind of warming up to me a bit. Hobbes just can't get enough love. He was an abused stray, and has been with us for nearly 3 years--he's an old, sweet guy, who will literally hold a guest hostage--by making them pet him for literally hours (3 was his record). Willi and Loki (brothers) are angels, too.
