I don't really think it matters that much, any beardie can be loving with proper care and attention. I have a male, but females make great pets too! I would choose the one that looks the healthiest and not worry about gender unless you want to breed.
I agree that it really doesn't matter as long as it is healthy. We have 1 female & 3 males and they are all amazing & loveable, all have their own unique personalities. The only difference that I have seen is that the female is more curious about things and is much more relaxed when we take her outside and places than the males are, although that could just be her individual personality. You can't go wrong in what sex you decide to get but might want to bare in mind that babies are more particular with their needs. Let us know what you decide. :wink:
