Which rooster?

I have two roosters and ten chickens so I have to get rid of one. The question is which. i want to make a good decision and pick the best one but I don't know what to look for. Do I want the one that can be held easier but doesn't lead the pack of smaller chickens that are the rooster's age and is smaller or do i want the one that is more skittish and doesn't like to be held but leads the young chickens and is fatter?

What would you do and what traits are desirable for a rooster? I know you want to be the boss but don't you want a chickens that will run the chickens?

By the way, neither of my roosters lead my older chickens. Not yet anyway.
