It really depends on what you want, both are fun pets, Uros eat veggies only, require high basking spots, large cages and grow pretty slow. Beardies eat tons of food in their first year (crickets, worms, dubias) some greens. As far as them being tame, you get out of them what you put into them. You really can't go wrong with either one IMO. Read multiple care sheets on each animal, look up caging requirements, tons of pictures online, scour other forums for info then make the best decision you can.
