Male or female cat? Which one makes better pet?

I have noticed a distinct difference in males and females in one specific area. All of my life, it seems male cats tend towards female humans, and female cats tend towards male humans. It is certainly not a hard & fast rule, but it normally holds true. Find couples living together, and most of the time it works out that way. We have three cats, 1 female (I belong to her), the 1st male, (my wife belongs to him), and another male, who is mostly independent, but has adopted our oldest daughter for the most part. These are spayed and neutered cats by the way, done at a fairly young age. I have never seen any real personality differences in most "fixed" cats I would say is sex related. An adult un-neutered male, is a wholly different story, as is an un-spayed female to a lesser extent.
