Personality. I'd like to be a combination of all of them, but if I had to choose, I'd rather be a nice/personable person who's the dullest crayon in the box.
I said personality...the reason being is that I would assume with a great personality, I could better get along with people. I find that I have a hard time relating to them. The thing is, in my head, I can relate to anyone, I can assume the role of anyone, I can imagine what it's like to be anyone, but when it comes to actually translating that into the real world, it doesn't happen.
