I have two BO hens. One of them I'm quite fond of. She is friendly and curious, always the first to come hang with me when I'm out in the backyard, chattering away to me the whole time. I've become used to her conversational tone as she expresses either surprise or curiosity about what I'm doing. The other is personality-less, sad to say. She's just kind of "there". Doesn't approach us, shows no interest in us, doesn't do chit-chat. As long as she lays well when the time comes (she's currently only 3 months old), I'll be happy with her but I don't have any particularly fond feelings for her. I also have a BR rooster and a PR hen. The rooster is the friendliest bird I've ever had. He comes at a run whenever I go outside and hangs so close to me I've almost stepped on him a few times. I can reach down and pick him up or pet him and he seems to actually enjoy it. He eats gently out of my hand but hangs with me even if I don't have treats. The hen is only 10 weeks old but has always been my favorite among the chicks I got. In the brooder she was the only one who ever approached me to eat out of my hand, and even now that she is outside, she is still likely to run up to me or follow me around. She has more personality than the RIR or Red Star that she has grown up with, and is definitely the dominant hen among the three.
If I were you, I'd probably get both, but if that isn't an option and you do have to choose one I don't think you'll be unhappy with either. Only you can know whether egg-laying or broodiness is your top priority but if you want both, get both varieties, since a hen that is broody doesn't lay so if you have both you can still get eggs while the broody hen is sitting.
