Production breeds - who has the best personality?

[Spring-Chicken]

Red sex links, black sex links, cinnamon queens, Rhode island reds, Leghorns...

All of these breeds/crosses have reputations for excellent egg production. If I were to choose ONE egg factory hen to keep in my flock (the rest would be pets, not necessarily good producers), which breed is least likely to peck, bully, run & hide, or generally put herself on the cull list?

I really like the red star for egg production. I have two in my small flock, and they both have a pleasant nature with the other. They do produce eggs like crazy. I just got rid of two of my RIR. They were bullies. I liked their egg production as well, but they really picked on one of my Red Stars and the Maran.
