COI and low Wycliffe are touchy because many of the top winning poodles in conformation have higher Wycliffe's and COIs. Not all of them, but most. Often they are so closely related as to share 50% of the genetics with each other.
Desjardins is breeding traditional poodles that are good looking. They talk about health, but I would ask what testing they do and if it is posted on ofa. Their dogs look nice to me.
Crabapple Downs is breeding nontraditional poodle colors and dabbling in moyens (medium poodles). Some concentrate on that for health (mixing up the colors and types increases genetic diversity and often immune system health), some do it for experimentation and fun, some do it for the money. But, the poodles are not as nice conformationally. You can't get around that fact, but most people wouldn't know a good poodle from a bad. For a pet that shouldn't matter too much.
Keep in mind that show breeders, like Desjardins, who has the better looking poodles of these two, will have many pet puppies with each litter. If they do health testing and are focussed on maintaining good temperaments in their breeding program, I might go for them over the other. Good show breeders, and there are many, try to breed healthy poodles who are good representations conformationally that have great temperaments. They won't sacrifice conformation in their goals, but they won't purposefully breed unhealthy dogs.
I would call Desjardins and ask about health testing and temperament. Ask about COI and see what they say. I personally like their dogs. The other breeder appears to be a pet breeder only. That's fine, but the dogs don't look quite as good from a looks only standpoint, but their personalities may rock.
I have a poodle with a low Wycliffe who has an extremely diverse pedigree. She is the smartest, healthiest, most athletic dog I have ever had. Her personality is fabulous, but she is also high energy. She rocks.
But, she is not perfect conformationally- a little long, a little short and a small girl. I also have a traditional looking black show style standard poodle. He is a thing of beauty, super sweet and seems very healthy. People stop me in the street with him, but not so much with her. He has a very low COI, but a higher Wycliffe. I offer this because you need to decide what you are looking for. Desjardins poodles are more like him. You will have to meet the dogs to assess their personalities.
Just my opinion, of course.
