People try different breeds, over time. The have great experiences and some not so great experiences. Much of the time, the outcome depends as much on the source of the birds, frankly, as to just how true to the breed and how true to the behavior associated with that breed the birds turn out.
As time goes by, we find, as humans with preferences of our own, that some breeds just "fit" us better. Much of it is subjective. We come to know a breed, feel comfortable with it, and sometimes adopt a breed as a reflection of our own lifestyle and personality.
An Orp will often be more laid back. A Red, a true bred Red, is actually a delightful, calm and friendly bird. But, these attributes may NOT turn out to be true with each situation, especially if one buys the chicks at feedstore reseller of hatchery stock. One simply has no way of knowing the temperament of the parent stock. It can be a roll of the dice.
An Orp from a hatchery source may end up a horrid layer and a big consumer of feed. A so-called red from a hatchery may turn out to be a prolific layer, but be flighty and ill tempered. It can range all over the map. These and a dozen other reasons make it difficult to make sweeping statements and make recommendations. Hope you understand.
Try some of each. That's the very best way. You may find you eventually one suits you much more than the other. Or, you may find you prefer neither of them.
