I have both males and females and to me it doesn't seem to matter. What it does seem to matter are a couple of variables. The age of the snake (hatchlings can be a little snippy), how many times its been handled, and feeding habits.

Since it sounds like your considering on getting a bp. I think you should ask yourself a few questions so you have a better idea what to aim for.

1. Do you plan on breeding your bp?
2. Do you want a normal or a morph?

The reason its important is so your aware of somethings. I wish I planned a little better myself. I first just wanted a pet and than later, I jumped into wanting to breed. So:

If your planning on breeding it takes 3 yrs for a female bp to be ready for breeding. Females cost more than males, so if your planning on just a pet I would aim for a male.

Morphs are beautiful, but depending on your budget they can break your bank. Normals are less expensive and just like morphs make wonderful pets. Many people get normal females in the intention to breed them to a male morph to get lots of morph babies, because males are less expensive.

Good luck and hope to see pics of your new baby!
