There's like 3 things basically the same (ISA brown, Golden Comet, Cinnamon Queen), all red sex links, and they are the best all rounder you can ask for. Best layers, not broody, docile. I've had just about everything, but this year just raising random mixes I got as eggs to let the kid incubate.
So I think you already found the best. I didn't mean to refute anything you wrote, just adding some context for passer-bys.
