I have 2 beardies, three leos, and a true fire skink.
Beardies:
Jace and Zy are great. Always sweet and ready for a cuddle. Sometimes, when they don't want to cuddle, they will get away. Beardies know very much what they want and if what they want isn't what you want, guess which one of us is going to get what they want? :lol: I never had a serious problem with my beardies except for when I first got Jace. He was going through his adolescence phase, but luckily I nipped it in the bud before it became a huge problem. He did try to bite me and hiss.
Leopard Gecko:
What I like about leopard geckos is that, at first, they are very skittish. But with time and patience, they are more than willing to chill on your shoulder and watch television to you. A good bit of people own both leos and beardies for the fact that when the beardies are going to bed, the leos are waking up. They also don't go through brumation. So, while your beardie is passed out and sleeping and not wanting to be handled, you have your little leo pal. You just have to put a little more work into them than you would with your beardie to tame them.
True Fire Skink:
I love my little girl. She's up during the days as well, but you almost never see them. They hide in a loose substrate so you have to go digging to take her out. She requires constant handling to keep her tame and as soon as you stop, she will go wild again. She's a little sweetie and very easy and low maintenance to take care of.
