Honestly, I'd go with the female!
I don't regret getting my girl at all. I bought her as my first, and she is the best. Definitely my favorite! She's captured the heart of everyone that meets her as well to the point where when I move out soon my mom is wanting to keep her here >_> She is so cute, and loves to follow me around, and will follow my finger on the glass, and does this "great white shark" impression when she eats! She's quite the character, and has WAY more personality than my male.
I think they are more "socialized" because females stay there WAY longer, so they come in contact with tons of people daily, but that's just a guess.
