I don't know about "all" the Avics (and with the standard "different personalities" disclaimer), but I can tell you about what I've noticed about our brood.
Avicularia avicularia: one of the most laid-back of the bunch, and generally the slowest-moving unless startled;
Avicularia diversipes: probably the "Nervous Nelly" of the bunch, a little bit high-strung and prone to hiding;
Avicularia huriana: Halo's my little sweetie - also kind of prone to staying in her hide, but when we moved her from pill bottle to acrylic box, we had a wee bit of a problem. Instead of going into the box, she came out of the pill bottle and onto my hand. Walked around a little bit as if investigating, and then decided that she was comfy and didn't want to leave!
Avicularia versicolor: we've got two, and they're both pretty much middle-of-the-road, between
A. diversipes and
A. avicularia. One of them will come out and take a short walk on my hand (although I think she'd like to walk a lot further than that), the other one is more of a "touch-me-not", and doesn't care to be bothered all that much.
So in all honesty, I haven't noticed "that" much of a personality difference between our Avics, other than the hiding and "leave me alone" differences, which could just as easily be explained as being scared of that big, noisy monster who comes by and shoves crickets in the boxes, or spritzes water in their homes.
Short answer is, we've only got one tarantula whose personality has been "by the book". Get whatever kind you want, and their personality will grow on you!
