I use the Flockstar app to track my hens' laying. According to the app, the top 3 layers under my golden comets (which I will never get again because of their grumpy demeanor and projected short lifespan) are the cuckoo marans, barnevelder, and hatchery buff orpington in that order. The marans is very friendly to me but can be witchy to the other hens, the barnevelder is terrified of people but very sweet to the other hens, and the orpington is very kind and friendly to both people and the other hens. They all have to live confined to a run or mobile tractor and they all bear it well, but I think the barnevelder would be happier free ranging. It's only my first flock but I'm glad I went with a mix rather than just one breed, if you end up disliking one or two breeds you aren't stuck with a whole flock of them.
